Hi Gran_Lev and welcome.
EDIT:
do not do it.
explanation at the end of the post
I have no real experience with that, but when I look to config folder, for me it is very clear.
casaOS config folder and main file is here:
/etc/casaos/app-management.conf
See part:
[server]
url1
url2
url1 is casaos.app/store/main.zip - download and see 09/24/2025 last update
url2 …master.zip … is github with last write time 10/09/2025 so last apps configs and urls… are in this pkg on github.
Try to comment/delete url1 (casaos.app). Comments are: line starts with symbol: #
reload casaos service:
sudo systemctl restart casaos
If nothing happens, try to reboot Host.
Please share with us, if it helps You.
Before upgrade Immich, be sure, You have backup. Path to folder, where sit Your data is little bit described here.
EDIT:
I do not understand, that there are 2 stores: (main)store + bigbeartechworld. Remove main store You lose access to 145 apps.
Better do more then 1 reboot for update big bear store app. Restarting service casaos (systemctl restart casaos) is not enough for refresh.
