i had an issue installing ipconfig on fedora i tried to send this command:

quotacheck -avugm


but i got this error:

bash: quotacheck: command not found


so to fix this, i had to run it like this:

/sbin/quotacheck -avugm


after i did that, it worked

quotacheck: WARNING - Quotafile //aquota.user was probably truncated. Cannot save quota settings...
quotacheck: WARNING - Quotafile //aquota.group was probably truncated. Cannot save quota settings...
quotacheck: Scanning /dev/sda3 [/] done
quotacheck: Checked 7485 directories and 71786 files



so the next step was to send this command:

quotaon -avug


and yet again i got this error again. so guess what, ahhaha, you guess it, you need to add the /sbin to make it work

/sbin/quotaon -avug


after i sent it, i didnt get the error anymore
/dev/sda3 [/]: group quotas turned on
/dev/sda3 [/]: user quotas turned on


hope that helps you
