What could possibily be causing it? Etar on arm android syncs it! Both are running Thndebird Supernova 115.8.1 64bit deb. Is it a thunderbird thing or a Kubuntu thing? Is it a amd thing? Is it a LTS thing?)

[15:36] <kpaco> hi, how long takes an kubuntu installation from USB? I see now the screen "Detecting file systems...100%" but nothing else happens. Did the installation already finished?
[16:11] <mparillo> If you have a big hard drive attached to a slow computer it can take hours to figure out which partitioning schemes to offer.

[17:51] <user|2> Hello, how do I uninstall your operating system and install another one?
 in general you do not need to uninstall the previous operating system. By choosing the right options in installation phase, you can either install the systems side by side if you have the storage available or you can format the drives and perform a clean install which will not leave any files or even the file system of the previous installation.
 In kubuntu, this is done during the setup process in the Disk Setup phase and "Guided - use entire disk" is likely the option you are looking for. It will erase the previous OS and all files on the drive.
 If security is a concern, you can also overwrite the disk with zeroes. This is sometimes done because deleting a file does not actually delete a file, nor does formatting a disk destroy the data. The data still exists on the drive, the section which tells where files are just has no mention of the physical location of the files and they can sometimes still be recovered.
 From what I remember, this option might be available during installation. But it is rather slow and usually unnecessary, unless you are selling or donating a drive to someone else.
