After I started the upgradation, The steps like downloading the new packages, installing the new packages went well without any error. After that step, My software update app got freezed and it remained freezed for like 2 hours almost. Then I force restarted my system with restart button. But after restart, it was Ubuntu 18.04. So I'm not sure if the upgradation was completed successfully or not. My files are safe afer the restart. But how can I be sure that everything is okay. Can anyone please help me about this matter?
My /etc/apt/sources.list looks like
deb http://archive.ubuntu.com/ubuntu bionic main universe restricted multiverse
deb-src http://archive.ubuntu.com/ubuntu bionic main universe restricted multiverse #Added by software-properties
deb http://security.ubuntu.com/ubuntu/ bionic-security main restricted multiverse universe
deb http://archive.ubuntu.com/ubuntu bionic-updates main restricted multiverse universe
Thank you.
do-release-upgrade
,update-manager-core
or other? I would login via terminal andsudo apt update
to validate the sources are read correctly (watching the output), then possiblysudo apt dist-upgrade
in hopes of continue, but this step would possibly vary on what method you used to release-upgrade.sources.list
does not fill me with confidence, because it looks modified; there should be loads of instructions in the form of comments there. Regardless I'd do what I said (sudo apt update
which is mostly to ensure the output looks correct), thensudo apt dist-upgrade
in the hopes it would upgrade any packages not upgraded. Reset button I take as being a power-button (did the magic SysRq not work? or were they not tried? even if you don't remember the keystrokes, it's worth it to use another device to look up how to use them when necessary)sudo apt update
is giving an error likeW: GPG error: http://download.opensuse.org/repositories/home:/Horst3180/xUbuntu_16.04 Release: The following signatures were invalid: EXPKEYSIG 5A7D1D38BEB6D886 home:Horst3180 OBS Project <home:[email protected]> E: The repository 'http://download.opensuse.org/repositories/home:/Horst3180/xUbuntu_16.04 Release' is not signed.

sudo apt dist-upgrade
went well without error. I'm also worried about thesources.list
. I used the restart button ( there is a small button on cpu of my desktop, just bellow the power button to force restart the system). So what should I do at this point to be sure everything is okay?
