ERROR: unable to publish: stat None: no such file or directory

[Vitexus]

Strange error when publish command is run using TMPDIR

Detailed Description

Publish command

aptly publish snapshot  -batch -component=backports,borrowed,main,spoje -distribution=focal focal-backports_2022-03-14 focal-borrowed_2022-03-14 focal-main_2022-03-14 focal-spoje_2022-03-14 focal-all-2022-03-14

Fail when run by ansible (with TMPDIR=~) When same command started by hand everything goes well:

jenkins@vyvojar:~$ aptly publish snapshot -component=backports,borrowed,main,spoje -distribution=focal focal-backports_2022-03-14 focal-borrowed_2022-03-14 focal-main_2022-03-14 focal-spoje_2022-03-14 focal-all-2022-03-14

Please setup your webserver to serve directory '/var/lib/jenkins/workspace/RebuildDebRepo/public' with autoindexing.
Now you can add following line to apt sources:
  deb http://your-server/focal-all-2022-03-14/ focal backports borrowed main spoje
Don't forget to add your GPG key to apt with apt-key.

You can also use `aptly serve` to publish your repositories over HTTP quickly.

But ansible run fail with messages:

"stderr_lines": ["ERROR: unable to publish: stat None: no such file or directory"]
"stdout_lines": ["Warning: publishing from empty source, architectures list should be complete, it can't be changed after publishing (use -architectures flag)"]

Context

I thing, this is error.

Possible Implementation

substitute the '~' character in 'TMPDIR' variable to realpath of home directory

OR change message to:

ERROR: unable to publish: stat temporary directory None: no such file or directory

[r4co0n]

I ran into this problem as well, I let Ansible make sure that TMPDIR is set for my user running aptly commands, fully expanded. If you configure rootDir deviating from the default, e.g. to /opt/aptly, some temporary files end up in /opt/aptly/tmp, while others are written to TMPDIR - Setting TMPDIR to <rootDir>/tmp makes sure everything ephemeral ends up in a single place.

My wrapper (stupidly) ensures this state on every call.

[r4co0n]

Please note that environment variables should contain expanded paths, in your sample, $TMPDIR should be /var/lib/jenkins, your $HOME, instead of ~.

And you probably do not want to use home as your temporary directory, but create some subdirectory, maybe /var/lib/jenkins/tmp. Or just set it to /tmp, which should already exist.

There are many applications not doing the expansions you are used to when using a shell.
