Upgrade of LibC, Breaks PowerShell Snap Package

Asked by Mark Crouch

I filed a post on Ubuntu Forums with a I experienced testing Focal Ubuntu - Link below.
I have performed a temporary fix - I just want to notify the dev of the bug.

Summary 14/03/20 AM - Upgrade of libc caused an error with librt.so in starting the powershell snap.
Reverted to an earlier ZFS Snapshot, apt-mark held all libc upgrades.
Upgraded my system and pwsh started OK.

My /var/crash folder is empty

There is a known problem with updates of libc6 on focal (related to libcrypto.so), Bug #1867431

I assume that this is also the cause for your case, although I am not completely sure.

My Dell Latitude has LibC packages held, which allows the PowerShell to run.
On my Desktop machine, I have allowed the latest LibC packages to upgrade and have replecated the error - output:

$ pwsh
Failed to load �&p, error: /snap/powershell/104/opt/powershell/../../lib/x86_64-linux-gnu/librt.so.1: undefined symbol: __clock_nanosleep, version GLIBC_PRIVATE
Failed to bind to CoreCLR at '/snap/powershell/104/opt/powershell/'

Hope this helps.

This seems to be an error in the snap file, and not the glibc libs of Ubuntu.

I left a comment on the first link you gave (issue 60), just so they're aware that it's not just Suse Tumbleweed that it's happening on.

Thanks for your replies Manfred.
