| lubot | <The_LoudSpeaker> Namaste! dega | 04:59 |
| lubot | <tbs> hello, i need support, i tried simple screen recorder, my voice was too low, not comfortible to listen, i thougt there was problem about my mic, 2 days ago as i shared here i put ram and ssd to laptop and they installed win10 to show me it works but there was bios problem cuz of ram, so i couldnt install lubuntu, that night, before going | 08:22 |
| lubot | compiter shop to repair bios, i tried my mic with OBS, it was good really, 4x better than when i use at lubuntu, now im trying it again at lubuntu with OBS and it s not working well again. | 08:22 |
| lubot | <tbs> in short there s problem at lubuntu about getting my voice via mic | 08:22 |
| guiverc | @tbs, I have no experience with recording voice via mic, but I'd suggest looking in pavucontrol (or pavucontrol-qt if using modern lxqt) to increase volume.. If i look in my own, i gives blank and "No application is currently recording audio" but I'd hope you'd have options there with OBS etc installed | 08:25 |
| lubot | <tbs> guiverc, it s not about increasing voice, cuz i also tried it before, but it just reduce its quality | 08:28 |

| nmzm | Hello everyone :) | 17:48 |
| wxl | heyo nmzm | 18:06 |
| tipreg | Hello, desperate here. I had lubuntu on a machine with 500G almost full hard disk. An idiot thought he could just take it and install windows on it. Is there any way to recover the data? | 19:01 |
| wxl | if they made a new partition, quite possibly. if they throttled over the install, no… | 19:02 |
| tomreyn | tipreg: only what was not overwritten probably. create an image of it, store it elsewehre, use testdisk against the image | 19:02 |
| wxl | i mean i guess there's some remote possibility some of the data could exist in free space, but it would take some hardcore forensics to even get to that | 19:02 |
| tomreyn | and... you need to always have abackup of any data you consider relevant, not only when there are people around who might install windows over your precious single copy. | 19:03 |
| tipreg | yes, just never imagined this could happen | 19:03 |
| wxl | thus the word "always" XD | 19:04 |
| tipreg | So is there a good chance i can recover most of it? | 19:04 |
| tomreyn | there are many other scenarios which could have had a comparable result. | 19:04 |
| tomreyn | there's a chance you may be able to recover parts of it, but without more details it's impossible to tell. | 19:05 |
| tipreg | he just installed windows overwriting lubuntu, nothing else (!) | 19:06 |
| tomreyn | and recovery of those parts will most liklely involve work by someone with a minimal level of experience in forensics. | 19:06 |
| wxl | yes, that | 19:06 |
| mycrap | will gparted recover anything in that situation? | 19:06 |
| wxl | you would first need to do what tomreyn suggested: image it somewhere else (`dd` is what i would use but it's a dangerous tool) | 19:07 |
| tipreg | I feel better for that "what was not overwritten probably" | 19:07 |
| wxl | well that's the other thing: data is not stored sequentially | 19:08 |
| tipreg | Why is it better to use testdisk on the image rather than directly on the disk? | 19:09 |
| tomreyn | the most common mistake after such an event is that users continue to write to the storage which is afected, such as by rebooting form a system storewd on it, or otherwise mounting data from it in read-write mode. if you do this, you're actively working against the goal of data recovery. thus you need to create an image first of all. | 19:09 |
| tomreyn | sorry about the typos, hope you can read it nevertheless | 19:10 |
| tipreg | ok, can i please ask you for an exact step-by-step | 19:10 |
| tipreg | also i am not sure what i will be using (usb?) | 19:11 |
| tipreg | (pendrive) | 19:11 |
| tipreg | I cant afford aforensics expert, have to do it myself | 19:12 |
| tipreg | unfortunately | 19:12 |
| tomreyn | any storage which can handle several writes and won't loose the data soon (you can create multiple copies and store it on different storages once you have created one copy) | 19:12 |
| tomreyn | which impact does it have to your life if this data is lost, if i may ask? | 19:13 |
| tipreg | Do i create the image from windows or from a live-linux? | 19:13 |
| nmzm | Guys, is there a way to check which version of libsdl2-mixer is installed? Not from the repository | 19:13 |
| tipreg | 5 years of work thrown in the garbage | 19:14 |
| tomreyn | hmm, and you don't even have an older backup of it? | 19:14 |
| tipreg | maybe some parts, but not most of it | 19:15 |
| tipreg | yes my mistake | 19:15 |
| tipreg | here | 19:15 |
| tomreyn | i don't mean to judge, i'm just asking. | 19:15 |
| tipreg | I should have had it fully backedup | 19:15 |
| tipreg | but this scenario was completely unpredictable | 19:16 |
| tomreyn | no, loss of data from a single storage is very predictable | 19:16 |
| tipreg | I mean who would do something like that... just idiot isn't enough... | 19:16 |
| tomreyn | the cause is unexpected, i agree | 19:17 |
| tomreyn | but you generally need to prepare better in the future | 19:17 |
| tomreyn | which other storage media do you have available to store those 500GB on? | 19:17 |
| tipreg | usbdisk | 19:18 |
| tomreyn | flash storage is an option but an SSD or HDD would be better | 19:18 |
| tipreg | yes externaldisk i mean | 19:18 |
| lubot | <wxl23> @nmzm [<nmzm> Guys, is there a way to check which version of libsdl2-mixer is installed …], Are you saying you know you didnt install from the repos? If not, where? | 19:18 |
| tipreg | (sorry) | 19:19 |
| lubot | <tbs> 500gb flash storage? so they made it too. i wonder how expensive it s | 19:19 |
| tipreg | consider me a beginner, actually I am | 19:19 |
| nmzm | lubot: Compiled from source code and then: sudo make install. So dpkg -l | grep sdl can't see it | 19:20 |
| nmzm | But it's installed in the system | 19:20 |
| lubot | <wxl23> @nmzm [<nmzm> lubot: Compiled from source code and then: sudo make install. So dpkg -l …], Where did you get the source? | 19:20 |
| nmzm | Lubot: From the official website I believe. From here -> https://www.libsdl.org/projects/SDL_mixer/ | 19:22 |
| tomreyn | tipreg: no worries, you're doing well. i need to persist on this, though: which kind of storage is this external, usb connected storage? is it a classic ultra-portable flash storage "usb stick", is it a (larger in physical dimensions, at least 1.5 inch width) SSD, is it a (even larger in physical dimensions, at least 2.5 inch width) HDD? | 19:22 |
| tomreyn | we can also find out when you have it connected. | 19:22 |
| tipreg | yes the larger one (dont have it right now though) | 19:22 |
| tipreg | it's a classic external hd maybetoshiba | 19:23 |
| tomreyn | tipreg: okay, for now tell me whether anything is running off this 500 GB storage you need to recover data from | 19:23 |
| nmzm | Lubot: I can see that ist's 2.0.4 on the website, but I need to add a check if it's installed in the script. Like: If sdl2-mixer=2.0.4 - continue, else: error(example) | 19:23 |
| tipreg | sorry i dont undertsnad what you mean | 19:23 |
| tipreg | running off? | 19:24 |
| tipreg | (also english not my first language) | 19:24 |
| tomreyn | tipreg: you mentioned a windows installation, you are on this lubuntu channel so you probably also have an ubuntu installation on this computer. is it a dual-boot system? | 19:24 |
| tipreg | no, this is another computer | 19:24 |
| tomreyn | is the computer with the 500 GB disk attached to it currently running? | 19:25 |
| tipreg | I dont have the externaldisk nor that "nowwindows machine" here with me in this moment | 19:25 |
| tipreg | the nowwindows machine is turned off (and not here with me now) | 19:26 |
| tomreyn | ah, so we can only discuss what your next steps should be, but can't guide you live now | 19:26 |
| tipreg | yes - though would have been nice i guess | 19:27 |
| tipreg | i mean nice to have you with me during the process | 19:27 |
| tipreg | but i'll try by myself and come back in case | 19:28 |
| tipreg | hoping to find you again | 19:28 |
| tomreyn | you can just come back here when you're about to do it, someone may be around, or if not here, then in #ubuntu | 19:28 |
| tomreyn | tipreg: so to keep it simple, you should have two separate external storages ready to image the 500 GB disk: | 19:29 |
| tipreg | yes maybe I'll do - but they (this computer and the other) are in different locations | 19:29 |
| tipreg | i have to move one | 19:29 |
| tipreg | ok so i am with you | 19:30 |
| lubot | <wxl23> @nmzm> Lubot: From the official website I believe. From here - [<nmzm> Lubot: From the official website I believe. From here -> https://www.libs …], See `strings` and `readelf` suggestions here https://unix.stackexchange.com/questions/58846/viewing-linux-library-executable-version-info#58849 | 19:30 |
| tomreyn | tipreg: one should be a bootable (l)ubuntu live system (which you could prepare now), the other should be a storage (ideally ssd or hdd) which can hold those 500 GB data. | 19:30 |
| tipreg | is it ok if the live system is on a pendrive? | 19:30 |
| nmzm | lubot: Thank you! | 19:30 |
| tomreyn | tipreg: sure | 19:30 |
| tomreyn | this won't take many sustained writes. | 19:31 |
| tipreg | possible problem: maybe that computer won'allow usb-boot (it's old) | 19:32 |
| tipreg | maybe only cd | 19:32 |
| lubot | <tbs> i thought 500gb flash disk would be more expensive | 19:32 |
| tipreg | cd-boot | 19:32 |
| tipreg | is that also ok? | 19:32 |
| tomreyn | tipreg: dvd should also work, i guess. | 19:32 |
| tipreg | which distro? | 19:32 |
| tomreyn | tipreg: what did you have running on it before windows got installed? | 19:33 |
| tipreg | afornsics one or just lubuntu? | 19:33 |
| lubot | <tbs> there s some data recovery specialezed distros at distrowatch | 19:33 |
| tipreg | before windows lubuntu | 19:33 |
| tomreyn | tipreg: do you know which version of lubuntu you had? | 19:33 |
| tomreyn | tipreg: it's ok to say "no" if you're not sure, i'm just wondering | 19:34 |
| tipreg | was an older lts, not sure | 19:34 |
| tipreg | LTS | 19:34 |
| tipreg | not sure exactly which | 19:35 |
| tomreyn | tipreg: just use the latest stable lubuntu then | 19:35 |
| tipreg | Ok so i launch tthe dvd with lubuntu on the windows machine and then? | 19:36 |
| tipreg | I connect the externald drive? | 19:36 |
| tomreyn | tipreg: actually it's probably better if you use lubuntu 18.04 LTS (atest LTS release), since 19.10 (latest stable release) has a different interface you're not used to. | 19:36 |
| lubot | <tbs> https://distrowatch.com/table.php?distribution=clonezilla | 19:37 |
| tipreg | ok | 19:37 |
| lubot | <tbs> ş found this | 19:37 |
| tomreyn | tipreg: once you have the system booted off it, you need to attach the other large storage device which can hold the 500 GB image file. | 19:37 |
| tomreyn | tipreg: test whether and ensure that you can write to it, as root. | 19:38 |
| tipreg | ok - the other device must be empty even if it's say 1tb ? | 19:39 |
| tipreg | or is it ok as long as it has 500G free? | 19:39 |
| tipreg | how should it be formatted? fat? ext? | 19:40 |
| === lubuntu is now known as Guest86789 | ||
| tomreyn | i would recommend it, but it's not required to be empty. you just need to be able to store the 500 GB there. you woill later also need to have some place to restore data that you recovered form this image. so if you want to store recovered data on the same device you have the image on (actually not an ideal situation, a separate storage would be better) then you'll need more than those 500 GB | 19:41 |
| tomreyn | i'd use an ext4 file system, or any journalled file system lubuntu supports, but it is less relevant | 19:42 |
| tipreg | even fat would be ok? | 19:42 |
| tipreg | I am confused because it's windows now | 19:42 |
| tomreyn | that's not a journalled file system, but if you have to use fat that can work too. | 19:43 |
| tomreyn | a windows alternative to ext3/4 is ntfs | 19:43 |
| tipreg | I mean the fact that it's windows now doesn't suggest to use fat? | 19:43 |
| tomreyn | no | 19:43 |
| tipreg | ok | 19:43 |
| tipreg | (sorry for stupid questions) | 19:44 |
| tipreg | :) | 19:44 |
| tipreg | so not even ntfs would be better? | 19:44 |
| tipreg | I mean ext is just as fine or better | 19:44 |
| tomreyn | don't try to access your old data using any of the file system or partition strcutures the windows installation created on the 500 GB drive, in fact dont try to access it at all other than by using the dd command | 19:44 |
| tipreg | not familiar with the dd command | 19:45 |
| tipreg | !dd | 19:46 |
| tomreyn | assuming the file system you will recover to is mounted at /media/myusername/my_external_recovery_filesystem and the 500 GB storage you want to recover is located at /dev/sdZ, you would use this command to create the image file: | 19:47 |
| tomreyn | sudo dd if=/dev/sdZ of=/media/myusername/my_external_recovery_filesystem/sdZ.image bs=8M | 19:49 |
| lubot | <tbs> will he create iso file of his 500gb? can i use this iso to reinstall same lubuntu system with its drivers and updates ? | 19:49 |
| tomreyn | no, tbs | 19:49 |
| lubot | <tbs> i mean if i do it on my system, not his | 19:50 |
| tipreg | ok so that creates the image (was thinking of xfburn) | 19:50 |
| tipreg | and then how to dotestdisk on the image? | 19:51 |
| tomreyn | tipreg: the hardest part will be identifying the imaging source and destination. "sudo lsblk" may help you there. | 19:51 |
| tipreg | should i bring it on the other (this) computer? | 19:51 |
| tipreg | I am not sure what you mean | 19:52 |
| tipreg | (last thing you said) | 19:52 |
| tomreyn | tipreg: concentrate on doing hte image first of all, this wilkl be a difficult task already. once you have this testdisk is the next step. | 19:53 |
| tomreyn | most importantly, be aware that dd is a dangerous utility. if you get those options wrong you may well overwrite the wrong storage and destroy more data | 19:53 |
| tomreyn | so make double sure (amybe get feedback here on this) that you got the if= and of= right | 19:54 |
| tipreg | the if is where i'm writng to and the of is where i'm writing from, right? (this is the possible mistake?) | 19:55 |
| tomreyn | tipreg: i guess your first step should be to prepare the lubuntu 18.04 bootable usb stick or dvd, bring it to the other computer, boot it off it, and login to the chat from there. | 19:55 |
| lubot | <tbs> first he can try to use dd command to create bootable usb disk so he can pratice ? | 19:55 |
| tomreyn | tipreg: if= IN file, of= OUT file. | 19:55 |
| lubot | <tbs> forexample with lubuntu iso | 19:55 |
| tomreyn | tbs: yes, if tipreg has an usb stick for this purpose (and not just optiocal media) then this could be done, feel free to guide. | 19:56 |
| tomreyn | tipreg: so if) is the source, of= is the destination, you had assumed otherwise. | 19:57 |
| tomreyn | *if= | 19:57 |
| tipreg | yes that's the possible mistake, any other possible mistakes? | 19:58 |
| tipreg | bs=8M ? | 19:59 |
| lubot | <tbs> if == input file … of == output file … usage example: … $ sudo dd status=progress if=name-of.iso of=/dev/sdb | 19:59 |
| tomreyn | tipreg: if of points to the wrong location, you'll write data there instead, possibly overwriting data or a full disk. | 19:59 |
| lubot | <tbs> this s basic usage of dd for creating bootable disk | 19:59 |
| tipreg | Ok, I will remember to double check there | 19:59 |
| lubot | <tbs> and i guess u may want to read it but im not sure ofcourse https://www.ostechnix.com/how-to-create-bootable-usb-drive-using-dd-command/ | 20:00 |
| tipreg | what is bs=8M ? | 20:00 |
| tomreyn | tipreg: bs=8M just means that the copying process will read 8 MB of data then write those, then repeat. | 20:00 |
| tipreg | ok, no mistake can be done there? | 20:00 |
| tomreyn | tipreg: not unless there are typos. ;) | 20:01 |
| tipreg | ok | 20:01 |
| tipreg | so this is what you meant when you said identifying the imaging source and destination | 20:01 |
| tipreg | ? | 20:01 |
| tipreg | or is there more? | 20:02 |
| tomreyn | this was just a complicated way of saying "make sure you get if= and of= right". | 20:02 |
| tipreg | ok | 20:02 |
| tomreyn | i'll have some food now, should be back later, good luck | 20:02 |
| tipreg | now we are at the testdisk part? | 20:02 |
| tipreg | ok | 20:03 |
| tipreg | thank you | 20:03 |
| lubot | <tbs> have a nice meal tomyern:) | 20:03 |
| lubot | <tbs> as a suggest u can use 1/3 of ur stomach for food, 1/3 of ur stomach for water, 1/3 of ur stomach for air, also 2 times eating for a day | 20:05 |
| tipreg | Is it easy to use testdisk? | 20:07 |
| tipreg | I mean can a beginner manage? | 20:07 |
| lubot | <tbs> do u know virtual box? | 20:09 |
| lubot | <tbs> u can try it there i guess | 20:09 |
| tipreg | Thank you all | 20:21 |
| tipreg | Will check log later in case anybody will have added something | 20:22 |
| tipreg | Good thing is I feel a little better | 20:23 |
| tipreg | :) | 20:23 |
| Sefa | hello everyone, i am experianceing trouble trying to install lubuntu on my device, i am on the particioning part and dont know how to progress. Help would be much apreciated thanks in advance | 21:03 |
| tomreyn | Sefa: hi, which lubuntu version is it, and what's the partitioning trouble about? | 21:06 |
| tomreyn | have you considered automated partitioning? | 21:07 |
| Sefa | i dont have the option for automated partitoning | 21:07 |
| Sefa | its the lates version | 21:08 |
| bwew253tgzwhbd | guys if i upgrade lubuntu 19.10 to 20.4 when 20.04 is officially released, will my sources.list also be updated ?? | 21:10 |
| lubot | <Mateusz Konieczny> Yeah, in 19.10 something is apparently broken. I also needed to partition manually. | 21:12 |
| lubot | <Mateusz Konieczny> I created small swap partition (aroung 8GB?) and all remaining part was mount point for / | 21:14 |
| lubot | <Mateusz Konieczny> It worked, but I admit that I am not sure is it the best solution. | 21:14 |
| lubot | <Mateusz Konieczny> AFAIK for hibernation you need swap larger than your RAM size, but hibenation never worked for me in Lubuntu anyway. | 21:14 |
| lubot | <kc2bez> If you have swap enabled when you start the installer the erase disk option will not be presented. | 21:15 |
| lubot | <kc2bez> You can turn swap off in the terminal before you start `sudo swap off -a` | 21:16 |
| lubot | <kc2bez> Erase disk will be presented as an option after that. | 21:17 |
| lubot | <Mateusz Konieczny> So it is side effect of removing "install lubuntu" from the main menu? | 21:17 |
| Sefa | my terminal tells me swao is not a command he knows | 21:18 |
| Sefa | my terminal tells me swap is not a command he knows | 21:19 |
| lubot | <kc2bez> Not sure I follow you there. It is because in Ubuntu based distros swap partitions are automatically mounted. The installer will not install on a partition that is mounted. | 21:19 |
| Sefa | how does one unmount? | 21:20 |
| lubot | <kc2bez> @Sefa [<Sefa> my terminal tells me swap is not a command he knows], sorry that should have been all one command. autocorrect got me there. swapoff -a | 21:20 |
| lubot | <kc2bez> We put a notice in our manual regarding swap. https://manual.lubuntu.me/stable/1/1.3/installation.html | 21:22 |
| Sefa | okay done, but i still only have the manual partitioning | 21:26 |
| kc2bez | bwew253tgzwhbd: The upgrade script changes the sources but if you have any ppas enabled they will be disabled during the upgrade process and you will need to re-enable them when it gets done. | 21:42 |
