Can you maybe elaborate on wether you did anything special yesterday or before this started happening

[matejay]

2 weeks ago i had some problems with upgrading packages and yunohost. Could it come from there?
Here are the logs: https://paste.yunohost.org/raw/diwedazadi

[Aleks]

Could be yes, did you do anything special to fix this ?

[matejay]

not for now. Because everything works besides that, I wanted to do it if I had more time for this

[Aleks]

Hmmokay but that log shows you were on yunohost 4.x but your first post indicates 11.x, so something major definitely happened since then ? x_x

[matejay]

I thought that I’m on 11.x because it was the first entry when I looked at the version under apt show yunohost -a. There are 2 other entrys which have the versionnumber: 4.4.2.14
