Subject: Re: 6.0.0-RC kernels trigger Firefox snap bug with 6.0.0-rc3 through
6.0.0-rc7
Hi, this is your Linux kernel regression tracker.
For the impatient: please shoot if you have a vague idea why 6.0 might
cause error messages like these when running firefox via snap:
> /bin/bash: /lib/x86_64-linux-gnu/libdl.so.2: unsupported version 0 of Verdef record
> /bin/bash: error while loading shared libraries: /lib/x86_64-linux-gnu/libdl.so.2: unsupported version 0 of Verneed record
Anyway, moving on.
CCing Marc, who's also affected, and the regression mailing list, as it
should be in the loop for all regressions, as explained here:

These?

Just wondering, as then I maybe should make it clearer that sending a
report to just the mainling list is a bad idea, as nearly nobody will
see this.

Hmm. I have no idea at all what kernel change might cause this and hence
don't know whom to ask to look into this. What really would help
tremendously: if someone could bisect the problem with a vanilla kernel.
Here is a rough guide (hopefully I sooner or later find time to write
one that is more user-friedly):

Anyway, to be sure below issue doesn't fall through the cracks
unnoticed, I'm adding it to regzbot, my Linux kernel regression tracking
bot:
#regzbot ^introduced v5.19..v6.0-rc3
#regzbot title Firefox snap fails to run ("undefined symbol" and
"unsupported version 0 of Verneed record" error messages)
#regzbot ignore-activity
This isn't a regression? This issue or a fix for it are already
discussed somewhere else? It was fixed already? You want to clarify when
the regression started to happen? Or point out I got the title or
something else totally wrong? Then just reply -- ideally with also
telling regzbot about it, as explained here:
https://linux-regtracking.leemhuis.info/tracked-regression/
Reminder for developers: When fixing the issue, add 'Link:' tags
pointing to the report (the mail this one replies to), as explained for
in the Linux kernel's documentation; above webpage explains why this is
important for tracked regressions.
Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
P.S.: As the Linux kernel's regression tracker I deal with a lot of
reports and sometimes miss something important when writing mails like
this. If that's the case here, don't hesitate to tell me in a public
reply, it's in everyone's interest to set the public record straight.
