`find: ‘/usr/lib/modules/6.1.0-25-amd64/kernel/drivers/xen’: Bad message` / `unable to truncate for updated status of 'security-misc': Read-only file system`

[Patrick]

Did you use the testers repository?

security-misc might need improvement:

find: ‘/usr/lib/modules/6.1.0-25-amd64/kernel/drivers/xen’: Bad message

There is on issue which might cause strange file permission issues (maybe in testers repository): file/folder permissions issue `d????????? ? ? ? ? ? .` | Firefox no longer starting (probably not not a Firefox issue) | caused by disallow registering interpreters for miscellaneous binary formats `sysctl fs.binfmt_misc.status=0` · Issue #267 · Kicksecure/security-misc · GitHub

Is fs.binfmt_misc.status enabled or disabled? Should be disabled (unfortunately). To check:

sudo sysctl -a | grep fs.binfmt_misc.status

Should show:

fs.binfmt_misc.status = enabled

Otherwise after next upgrade and reboot will be reset to disabled.

For debugging, could you please run this command after reproducing this issue?

sudo ls -la /usr/lib/modules/6.1.0-25-amd64/kernel/drivers/xen

But security-misc isn’t breaking DPKG / APT, because it does exit 0 (success) by design:

@nurmagoz

/var/lib/dpkg/info/security-misc.postinst: INFO: Permission hardening success.

@nurmagoz

dpkg: unrecoverable fatal error, aborting:
 unable to truncate for updated status of 'security-misc': Read-only file system
dpkg: error: unable to access the dpkg database directory /var/lib/dpkg: Read-on
ly file system
E: Sub-process /usr/bin/dpkg returned an error code (2)

Could even be (virtual) hard drive issues which can cause all sorts of strange issues. But this issue isn’t caused by security-misc or I don’t see how it could accomplish such an error. Also hard to image this being caused by PipeWire / PulseAudio.

Couldn't create temporary file /tmp/apt.conf.RVCvgd for passing config to apt-key

At this point, the system is in a pretty broken state. Does that fix itself after reboot?
