I ran sudo apt-get -y update && sudo apt-get -y upgrade
around 2020-03-04T15:00:00Z, then rebooted my computer. The dock (plank) didn't show up, and the file manager (pantheon-files) is totally removed from my OS. I tried to fix this by running sudo apt-get -y update && sudo apt-get -y install pantheon-files
, and it gave me the following log:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
pantheon-files : Depends: libplank1 (>= 0.11.89) but 0.11.4+git20190318.fb624c21-0elementary5.0.1 is to be installed
E: Unable to correct problems, you have held broken packages.
I checked the versions of libplank1, and at the time of writing this post, the highest version is 0.11.4-2 for Ubuntu Bionic.
How can I fix this?

sudo apt update
and post the output so that I can confirm you have all the right software sources? You should have the latest plank available from our os-patches PPA. In general, it's not a good idea to run apt commands with-y
because you won't get a chance to verify that the command isn't asking you to remove packages.apt update
output added.apt-cache policy plank
would also be usefulsudo rm -rf /var/lib/apt/lists/*
. Runningsudo apt update
after this will recreate those caches that seem to be causing issues and hopefully the new version will be available.
