using 64bit Jammy
I am getting the following error message:-
sonyuser@SonyVaio:~$ sudo apt-get check
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: The package zoom needs to be reinstalled, but an archive for it can't be found.
Any idea how I can get the archive needed?
Hi, @duncan 
I think that "zoom" in that error message ("E: The package zoom needs to be reinstalled, but an archive for it can't be found.") refers to the "Zoom Desktop Client for Linux". Assuming that's the case, I suggest that you download and install the latest version for Ubuntu from "Download Zoom for Linux | Zoom" - https://zoom.us/download?os=linux
You can find more detailed installation instructions at "Installing or updating Zoom on Linux - Zoom Support" - https://support.zoom.us/hc/en-us/articles/204206269
I hope that helps
Hi ricmarques
Thank you for your reply, I have tried that and get the following:-
"Software index is broken
this is a major failure of your software management system. Pleas check for broken packages with synaptic, check the file permissions and correctness of the file /etc/apt/sources.list and reload the software information with sudo apt-get update and sudo apt-get install -f"
Synaptic will not run, just comes up with zoom needs to be reinstalled.
I have done the following from the terminal:-
sonyuser@SonyVaio:~$ cat /etc/apt/sources.list

Hi again, @duncan
Hmmm... I suggest that you start by running the following command:
sudo apt-get update --fix-missing
... and then run (again) the following command (that you also executed):
sudo apt-get install -f
Please, reply again to tell us how that worked.
Those two commands are recommended in the "Fixing Broken Packages in Ubuntu/Mint/Debian" section of the following article / web page:
You may also want to read the following discussion here in the Ubuntu MATE Community, started in May 2021, by @mack87-dash (Sekhar Suman Dash):
... and, in particular, in that discussion, the following reply by the late "mdooley" /
Michael Dooley (who would unfortunately pass away in November 2021): How to fix "Software index is broken"? - #24 by mdooley where he recommended reading the following two articles:
Still, in that discussion @mack87-dash replied to Michael Dooley to report that running the command sudo apt-get update --fix-missing solved the issue:
I hope this helps
Hi ricmarques
Thank you for your continued help.
I tried the apt-get update --fix-missing & install which did not work.
But followed the dpkg configuration instructions in the "how to fix broken packages" which you gave me a link to, which did!
Everything appears to be working fine now.
Thank you very much for your help. 
Hi duncan
Thanks for reporting back I'm glad that you ended up solving your issue by following the instructions available in the "Fixing DPKG Configuration Issues" section of the "How to Fix Broken Packages in Linux - Make Tech Easier" article. By the way, was it enough to run the first command mentioned in that section to fix your issue:
" 1. Start by trying to force dpkg to reconfigure any broken or partially configured packages:
sudo dpkg --configure -a
... OR did you also need to run the other commands from that section to fix your issue?
" 2. If that doesn’t solve the problem, take a more forceful approach. Start by listing any packages that dpkg marked as requiring a reinstall:
sudo dpkg -l | grep ^..rThe above command will show you the packages that cause problems. For this next step, check and make sure that the packages marked for reinstall are really broken. Do a
sudo apt reinstalland pay attention to which packages fail to reinstall.3. For each package that fails to reinstall, get the name and forcibly remove the broken package:
sudo dpkg --remove --force-remove-reinstreq [package name]4. Dpkg should now be clean. Do a cleanup with Apt:
sudo apt clean && sudo apt update(...)
Hi ricmarques
I had to run all the commands to fix the issue, sudo dpkg --configure -a on it's own did to fix it.
Thank you again for your help
You're welcome, duncan By the way, when you wrote "(...) on it's own did to fix it. (...)", I assume you meant to write "on it's own did NOT fix it. (...)" instead. Am I right?
Yes, sorry a typo I stand corrected
