gmachine24Hi running 22.04.5 LTS headless server I get a message about a corrupt GPT table on /dev/loop5 and I'm not sure what to do or how to fix it here is more info: https://pastebin.com/Q2yjDgr016:28
gmachine24this is when running fdisk -l16:28
gmachine24I had similar messages recently show up for complete drives I backed up the partition table info for that drive but the problem has since disappeared without me *fixing* it16:30
patdkwell, first things first, what is loop516:32
patdkbut normally that issue is due to one of two issues, but since your throwing loop into it, who knows16:32
patdkfirst is, you made the drive larger or smaller than it used to be16:33
patdksecond is, you restored only part of the disk16:33
patdkthe gpt exists at the start and END of the drive, so if the end of the drive changes, you just basically erased half of it16:33
gmachine24I'm not that familiar with I know it's related to some snapd 16:33
patdknot related to snapd16:34
gmachine24well....16:34
patdkbut if you didn't use loop5 and something else created/amanged it16:35
patdkI wouldn't go messing with it16:35
gmachine24Yeah it seems to be related to snapd and this is what I read online in Ubuntu docs16:35
