[Resolved] KDE Application Platform

Hello everyone,
I am reaching out because I have an update that
isn't installing, and I can't figure out why since
there is no error message.

KDE Application Platform
The update to version 6.10 fails; it loops infinitely.

I am using linux version q4os-6.7-x64
Regards
[Resolved]

Re: [Resolved] KDE Application Platform

Are you updating through Discover, Flatpak, or the command line or some other tool ?
What exactly is the package name shown in the updater ?

Re: [Resolved] KDE Application Platform

Could you open a terminal and post the output of:
$ sudo apt update
$ sudo apt full-upgrade
$ flatpak update
$ flatpak list | grep "KDE"

Do other updates install normally in Discover.?

Try to clear local cached obsolete data and post back the result.
$ sudo flatpak repair
$ flatpak uninstall --unused
$ flatpak update
Reboot

Re: [Resolved] KDE Application Platform

I briefly saw this at startup:
Error Kmod_config_parse
But no error appears in dmesg

Re: [Resolved] KDE Application Platform

Hello everyone,

I think I've solved the problem attributed to

KDE Application Platform version 6.10 failing to install

After some online research, seeing that other distributions
had similar issues,it turns out that Tor Browser was blocking
the KDE Application Platform version 6.10 installation with
a request in a loop.

Here's the message: "Can't remove org.kde.Platform/x86_64/6.10,
it is needed for: org.torproject.torbrowser-launcher"

Once Tor Browser was uninstalled, this installation disappeared,
and other updates that I thought were blocked were installed.

Will this help anyone?

Regards
