[12:49] <JustCurious> Good morning, I am trying to upgrade Ubuntu MATE 18.04 to 20.04 but my update-manager doesn't "see" any LTS releases available :O
[12:50] <JustCurious> this is what happens in my terminal: sudo do-release-upgrade -d -f DistUpgradeViewGtk3 ---> There is no development version of an LTS available. To upgrade to the latest non-LTS development release 
[12:50] <JustCurious> set Prompt=normal in /etc/update-manager/release-upgrades
[12:50] <JustCurious> it's 2022 lol
[12:55] <sixwheeledbeast> why -d flag?
[12:55] <arraybolt3> JustCurious: Did you remember to do a "sudo apt update && sudo apt full-upgrade" first? And also, yes, drop the -d, that's not what you want.
[12:56] <arraybolt3> -d will try to upgrade you to a development release (the current development release being 23.04). If you want to upgrade from 18.04 to 20.04, you're not trying to go to a development release. (I think -d can also be useful for an "early upgrade" in one other situation, but this isn't that situation.)
[12:57] <JustCurious> oh, thanks about -d flag
[12:57] <JustCurious> I'll test doing an update and full-upgrade first
[12:58] <JustCurious> but I just want to upgrade to 20.04, not 19.10
[12:59] <sixwheeledbeast> make a 20.04 live image and install over the top is another option.
[13:00] <JustCurious> OK, I've done "sudo apt update && sudo apt full-upgrade", then sudo do-release-upgrade -f DistUpgradeViewGtk3, and same result
[13:00] <JustCurious> "Please install all available updates for your release before upgrading"
[13:01] <sixwheeledbeast> reboot and do-release-upgrade iwth no args
[13:01] <JustCurious> mmm
[13:01] <JustCurious> I reboot be right back
[13:01] <JustCurious> thanks
[13:05] <JustCurious> sixwheeledbeast I would like to make de process with the Graphic app
[13:06] <JustCurious> what if I execute do-release-upgrade with no arguments ?
[13:07] <JustCurious> must I upgrade to 20.04 previous releases ? 
[13:07] <JustCurious> it's tricky for me
[13:09] <JustCurious> when I execute "do-release-upgrade" the response is: "Please install all available updates for your release before upgrading"
[13:10] <JustCurious> I've done that already
[13:10] <JustCurious> xD
[13:19] <JustCurious> https://askubuntu.com/questions/1231570/cant-upgrade-ubuntu-18-04-to-20-04-because-of-please-install-all-available-upd
[13:19] <JustCurious> the most popular solution is: 
[13:19] <JustCurious> sequence from 18.04 to 20.04
[13:19] <JustCurious> sudo apt update
[13:19] <JustCurious> sudo apt upgrade
[13:19] <JustCurious> sudo apt dist-upgrade
[13:19] <JustCurious> sudo apt autoremove
[13:19] <JustCurious> sudo do-release-upgrade -d -f DistUpgradeViewGtk3
[13:22] <sixwheeledbeast> something must be blocking upgrade. the updates aren't complete or packages held back.
[13:25] <JustCurious> apt list --upgradable
[13:25] <JustCurious> opera-stable/stable 94.0.4606.54 amd64 [upgradable from: 87.0.4390.45]
[13:26] <JustCurious> it was that
[13:26] <JustCurious> don't know hot to upgrade this one though
[13:27] <JustCurious> it's "other software" non ubuntu releases
[13:28] <JustCurious> i've disallowed updates from that software, let's see what happens
[13:31] <JustCurious> it works now, thank you
[13:31] <JustCurious> bye
