I’m quite new to linux and fedora, trying to work my way trough issues myself, but here I failed. Some time ago I started to have this error in Software Center:
(the odd language says that it failed with opening the file due to input/output error)
It looked as updates were working, but I couldn’t install anything trough center. Or see installed software.
Recently decided to have a sit and fix it, reenabled repos, reinstalled nvidia drivers completely, finally I went to check yum.repos.d. And here surprise, I have no access to it:
Sorry, could not display all the contents of “etc”: Error when getting information for file “/etc/subgid-”: Input/output error
That file name is a backup file usually created when the system edits the file /etc/subgid during user creation or deletion.
You should be able to do sudo rm /etc/subgid- without harm to the system and then the error will be gone
That cumulatively tells me that something has corrupted the filesystem for that file. The next step is to get that file removed and the file system fixed.
Are you using btrfs or ext4 for your file system? The repairs are different for each.
fsck works on an ext4 file system but not on btrfs.
