Happy new 2023 Debian and openSUSE KDE teams, This issue is about plasma-discover and locale/language settings and hope this is not Debian-specific. I fixed up my plasma-discover and it starts now, again on Debian/unstable AMD64 with KDE/Plasma version 5.26.5 and fetches updates. Normally, I do not use plasma-discover for upgrading packages but it's nice to have graphical frontend to check what is available. All my swcatalog caches (Debian DEP-11 metadata) were updated via: root# appstreamcli refresh --force root# LC_ALL=en_EN LANG=en_EN appstreamcli refresh --force Now I see: root# LC_ALL=C ll /var/cache/swcatalog/cache/ total 21M drwxr-xr-x 2 root root 4.0K Jan 14 10:59 . drwxr-xr-x 3 root root 4.0K Feb 25 2022 .. -rw-r--r-- 1 root root 1.3M Jan 14 03:25 de_DE-local-metainfo.xb -rw-r--r-- 1 root root 9.7M Jan 14 10:59 de_DE-os-catalog.xb -rw-r--r-- 1 root root 998K Jan 14 10:13 en_EN-local-metainfo.xb -rw-r--r-- 1 root root 8.8M Jan 14 10:13 en_EN-os-catalog.xb (Re)Moved all user's appstream + discover caches before: user$ mv ~/.cache/appstream ~/.cache/appstream.old user$ mv ~/.cache/discover ~/.cache/discover.old Renewed APT packages repository via: root# apt-get update As you can see I have both de_DE and en_EN swcatalogs. If I run from Start > Apps > Discover or from konsole... user$ plasma-discover ...I always have de_DE software-catalogs visible. With en_EN locales... user$ LC_ALL=en_EN LANG=en_EN plasma-discover ...works fine. Is there a place where I can set locales/language for plasma-discover? I found: $ cat ~/.config/discoverrc [Window] geometry=0,0,1366,695 visibility=4 Cannot say if this is the correct config file as I have something like discover (hardware-info) tool also installed. $ man discover discover(1) General Commands Manual discover(1) NAME discover — hardware detection utility Thanks for any hints.
