gnomo223 Already tried eopkg check (and the rest of It) but It only shows me the help page to eopkg It, as well the same happens while in liveusb
Are you sure you're running the correct command? The following will look for broken packages and reinstall them:
sudo eopkg check | grep Broken | awk '{print $4}' | xargs sudo eopkg it --reinstall
Since you can't open the terminal app (if I understand correctly) you can open e.g. TTY3 by pressing CTRL+ALT+F3
, log in, and run the command there
Edit: In general it would probably be wise to try to remove your custom applet again, since that's what seems to have caused you these issues.
