Description Pavel Březina 2019-07-30 08:14:00 UTC
+++ This bug was initially created as a clone of Bug #1697267 +++

Description of problem:
Sometimes I can see failures when enabling/disabling features.
Even though there were not any manual changes to files.

e.g.
sh$ authselect enable-feature with-mkhomedir'
[error] [/etc/authselect/postlogin] has unexpected content!
[error] Unexpected changes to the configuration were detected.
[error] Refusing to activate profile unless those changes are removed or overwrite is requested.
Unable to enable feature [17]: File exists

sh$ authselect enable-feature with-mkhomedir'
[error] [/etc/authselect/dconf-locks] has unexpected content!
[error] Unexpected changes to the configuration were detected.
[error] Refusing to activate profile unless those changes are removed or overwrite is requested.
Unable to enable feature [17]: File exists

Version-Release number of selected component (if applicable):
authselect-1.0.3-1.fc30.x86_64

How reproducible:
I do not have deterministic reproducer.
Just run tests many times.

Additional info:
sh-5.0# authselect check
[error] [/etc/authselect/postlogin] has unexpected content!
Current configuration is not valid. It was probably modified outside authselect.

sh-5.0# diff -i /etc/authselect/postlogin /var/lib/authselect/postlogin

Thank you. I will try to reproduce it.

Upstream ticket:
https://github.com/pbrezina/authselect/issues/146

--- Additional comment from Pavel Březina on 2019-04-25 08:42:28 UTC ---

Steps to reproduce:

$ sudo gdb -quiet authselect -ex 'set breakpoint pending on' -ex 'b src/lib/files/system.c:428' -ex 'run select sssd --force' -ex 'shell sleep 1' -ex 'detach' -ex 'quit'
$ sudo authselect check
[error] [/dev/shm/authselect-install/etc/authselect/system-auth] has unexpected content!
Current configuration is not valid. It was probably modified outside authselect.

This message is a reminder that Fedora 28 is nearing its end of life.
On 2019-May-28 Fedora will stop maintaining and issuing updates for
Fedora 28. It is Fedora's policy to close all bug reports from releases
that are no longer maintained. At that time this bug will be closed as
EOL if it remains open with a Fedora 'version' of '28'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 28 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

--- Additional comment from Ben Cotton on 2019-05-28 23:57:06 UTC ---

Fedora 28 changed to end-of-life (EOL) status on 2019-05-28. Fedora 28 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.

YOU SEE WHAT HAPPENS WHEN YOU REFUSE TO FIX A PROBLEM PROPERLY IN FEDORA?

IT ENDS UP IN YOUR "Enterprise" OS, EL8:

    [error] [/etc/authselect/password-auth] has unexpected content!
    [error] Unexpected changes to the configuration were detected.
    [error] Refusing to activate profile unless those changes are removed or overwrite is requested.

I very much doubt /etc/authselect/password-auth has been modified by *ANYTHING* besides authselect, as it doesn't look like something systemd would bother with.

Just ridiculous.

authselect-1.0-13.el8

# cat /etc/authselect/password-auth

And look at this:

authselect cannot validate its own files

FIX IT.
