[SOLVED] Opera problem

Hello All!

For sometime I have not been able to update / upgrade or install any file as I keep getting the fallowing error on console:

ali@ali:~$ sudo apt-get update
N: '/etc/apt/apt.conf.d/'  '20auto-upgrades.ucf-dist' is not a valid file extention and it is ignored.
E: Signed-By crushing set of values (source https://deb.opera.com/opera-stable/ stable: /usr/share/keyrings/operabrowser-keyring.gpg != )
E: source list cound not be read.

I am almost sure that the problem is related to Opera browser that I tried to install but messed up. Even synaptic is giving the same error and do not work.

System info: Q4OS Bullseye Plasma
Linux 11

Your advises please...

Re: [SOLVED] Opera problem

First you need to edit out any sources related to Opera
Second you need to sort out the name and contents of the 20auto-upgrades file.

If you use Synaptic then open it and go to Settings>Repositories and uncheck anything related to Opera
If you use Discover or Muon or whatever then just do it there instead.

20auto-upgrades controls part of the unattended upgrades process.
It contains 2 lines which by default in Plasma are:-
APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Unattended-Upgrade "0";

In the folder /etc/apt/apt.conf.d/ look for files with the name 20auto-upgradesxxxxx
There should only be one and it is just 20auto-upgrades - anything else containing that name is not needed.
If 20auto-upgrades.ucf-dist contains the lines above then just rename it to 20auto-upgrades
If it needs editing to correct it then do so.

This is puzzling as I have never come across that file being touched by any software installation.

Re: [SOLVED] Opera problem

Hello Bin!

I can not start Synaptic as it gives the error message as

E: Signed-By clashing value set (source https://deb.opera.com/opera-stable/ stable: /usr/share/keyrings/operabrowser-keyring.gpg != )
E: Source list couldn't be read.
E: _cache->open() failed, please report

Can I not just delete everything about Opera? I don't need it.

Re: [SOLVED] Opera problem

OK then go to /etc/apt/sources.list.d

You should see something like opera.list which you could just edit and comment out the lines with a #

If that is not there then you may need to look in /etc/apt/sources.list for a line that mentions opera and remove/comment out that line

Alternatively open /etc/apt in Dolphin and use Tools>Open kfind
Look for files *.list contains opera - not case sensitive

The editing can be done by right click>open with kwrite. When you save you'll be asked for your sudo password.

Re: [SOLVED] Opera problem

Dear Bin,

The problem seems to have been solved.

As you advised I searched for the file in the /etc/apt/sources.list.d. The first one to be noticed was 

"q4p-opera-20220612xxxxx-Rlu.list"

Inside the file, there were 3 lines and the last one was

"deb http://deb.opera.com/opera-stable/ stable non-free"  which was not commented. I just commented it and now I don't get any error messages and also I can update with no issue.

Thanks a lot for your help!
