This issue arises during the boot process of Ubuntu 22.04. Despite the system operating normally without any significant performance drawbacks, I consistently encounter a series of error messages related to mount unit failures. The system check reports the following:
/dev/nvme0n1p7: clean, 2041902/42721280 files, 67243365/170864384 blocks[ 2.464992] /var/lib/snapd/snaps/canonical-livepatch_229.snap: Can't open blockdev[ 2.464992] /var/lib/snapd/snaps/canonical-livepatch_229.snap: Can't open blockdev[ 2.468568] /var/lib/snapd/snaps/chromium_2614.snap: Can't open blockdev[ 2.471267] /var/lib/snapd/snaps/core_15925.snap: Can't open blockdev[ 2.472090] /var/lib/snapd/snaps/core_16202.snap: Can't open blockdev[ 2.482007] /var/lib/snapd/snaps/firefox_3068.snap: Can't open blockdev[ 2.484331] /var/lib/snapd/snaps/firefox_3206.snap: Can't open blockdev[ 2.487835] /var/lib/snapd/snaps/gnome-42-2204_120.snap: Can't open blockdev[ 2.490344] /var/lib/snapd/snaps/gnome-42-2204_141.snap: Can't open blockdev[ 2.498566] /var/lib/snapd/snaps/slack_89.snap: Can't open blockdev[FAILED] Failed to mount Mount unit for canonical-livepatch, revision 229.[FAILED] Failed to mount Mount unit for chromium, revision 2614.[FAILED] Failed to mount Mount unit for core, revision 15925.[FAILED] Failed to mount Mount unit for core, revision 16202.[FAILED] Failed to mount Mount unit for firefox, revision 3068.[FAILED] Failed to mount Mount unit for firefox, revision 3206.[FAILED] Failed to mount Mount unit for gnome-42-2204, revision 120.[FAILED] Failed to mount Mount unit for gnome-42-2204, revision 141.[FAILED] Failed to mount Mount unit for slack, revision 89.These messages indicate an inability to open blockdev for various snaps during boot, followed by failures to mount their respective units.
While these errors do not seem to hamper the functionality of the OS, I am concerned about potential underlying issues that may not be immediately evident. Additionally, I am interested in understanding the cause of these errors and how to resolve them for a cleaner boot process.
Here are the troubleshooting steps I've already attempted:
- Checked the filesystem for errors using fsck.
- Ensured that all snap packages are updated to their latest versions.
- Attempted to manually remount the mentioned units with no success.
I would be grateful for any insights into the following questions:
- What could be the potential cause of these error messages during the boot process?
- Is there a way to fix these mount unit failures without impacting the current system stability?
- Are these errors indicative of an impending system issue that requires preemptive action?
Any advice or diagnostic recommendations would be highly appreciated!
