Comment 2 Piotr Mierzwinski 2025-12-02 23:43:23 UTC
Unfortunately nobody helped through 2 weeks :(

Finally I solved issue by my self listing packages to update:
$ apt list --upgradable

... and installing manually by copy pasting packages to command:
$ sudo apt install pkg_name1 pkg_name2 ....

and 2 times run:
$ sudo apt-get update

In result all updated:

$ sudo pkcon update

No help here after 4 weeks, but I thought at least I could co-miserate, same thing here,

Workaround:

sudo apt install neon-settings-2
sudo apt update


... then pkcon update works
