Tab completion warnings with ubuntu-bug when using alias for ls

[Alistair Cunningham]

When running ubuntu-bug on the command line, and tab completing the package name, the following warnings are printed:

/usr/share/apport/symptoms/dist-upgrade.py: No such file or directory
grep: /usr/share/apport/symptoms/release-upgrade.py: No such file or directory

This happens when following alias is set:

alias ls='ls -N --color=yes --time-style=long-iso'

Thank you for your bug report, the issue doesn't seem to happen on a new 19.10 installation though.
The file listed is part of apport-symptoms which should be installed by default, but even without it the tab completion works

[Alistair Cunningham (acunningham)]

apport-symptoms is installed, but this keeps happening:

# dpkg -l apport-symptoms

Weird, what's the output of
- ls -l /usr/share/apport/symptoms/dist-upgrade.py
(it should be part of the binary)

[Alistair Cunningham (acunningham)]

# ls -l /usr/share/apport/symptoms/dist-upgrade.py
lrwxrwxrwx 1 root root 26 May 17 16:32 /usr/share/apport/symptoms/dist-upgrade.py -> ubuntu-release-upgrader.py

[Sebastien Bacher (seb128)]

What about
-ls -l /usr/share/apport/symptoms/ubuntu-release-upgrader.py
-dpkg -S /usr/share/apport/symptoms/ubuntu-release-upgrader.py
-debsums apport-symptoms

The file should be there...

[Alistair Cunningham (acunningham)]

# ls -l /usr/share/apport/symptoms/ubuntu-release-upgrader.py
-rw-r--r-- 1 root root 214 May 17 16:32 /usr/share/apport/symptoms/ubuntu-release-upgrader.py

[Sebastien Bacher (seb128)]

Can you sudo apt install --reinstall apport-symptoms and see if that fixes the issue?

[Alistair Cunningham (acunningham)]

Still the same, unfortunately.

[Alistair Cunningham (acunningham)]

This also happens on 20.04. It now gives:

/usr/share/apport/symptoms/dist-upgrade.py: No such file or directory
grep: /usr/share/apport/symptoms/installation.py: No such file or directory
grep: /usr/share/apport/symptoms/release-upgrade.py: No such file or directory

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Maksim S (max-svo)]

ubuntu-bug actually greps output of ls
I have an alias for ls: ls -la
I can see output like this:
grep: /usr/share/apport/symptoms/-rw-r--r--: No such file or directory
grep: /usr/share/apport/symptoms/1: No such file or directory
grep: /usr/share/apport/symptoms/root: No such file or directory
grep: /usr/share/apport/symptoms/root: No such file or directory

I may be wrong but I think at the very least ubuntu-bug should call /usr/bin/ls and not just ls
Depending on user preferences, ubuntu-bug may even execute random software!

[Alistair Cunningham (acunningham)]

This still happens after upgrading to Ubuntu 20.10:

grep: /usr/share/apport/symptoms/dist-upgrade.py: No such file or directory
grep: /usr/share/apport/symptoms/installation.py: No such file or directory
grep: /usr/share/apport/symptoms/release-upgrade.py: No such file or directory
qgrep: /usr/share/apport/symptoms/dist-upgrade.py: No such file or directory
grep: /usr/share/apport/symptoms/installation.py: No such file or directory
grep: /usr/share/apport/symptoms/release-upgrade.py: No such file or directory

Note that that I have the following alias set for ls:

alias ls='ls -N --color=yes --time-style=long-iso'

[Alistair Cunningham (acunningham)]

This still happens after upgrading to Ubuntu 21.10. Is there any news on fixing it?

[Alistair Cunningham (acunningham)]

Is there any news on this? The problem still happens after upgrading to Ubuntu 22.04. There don't appear to have been updates since I last reported this for 21.10.

[Alistair Cunningham (acunningham)]

This is still happening after upgrading to 23.10.

[Benjamin Drung (bdrung)]

I can confirm the behavior by setting the ls alias. Unsetting the alias will solve the issue. So apport should be made more robust against the alias.

[Benjamin Drung (bdrung)]

Fix for it: https://github.com/canonical/apport/pull/222

You can apply the fix manually be editing /usr/share/bash-completion/completions/apport-bug and changing the function to:

_apport_symptoms ()
{
    local filename path symptoms
    for path in /usr/share/apport/symptoms/*; do
        [[ -e "$path" ]] || continue
        filename="${path##*/}"
        # hide utility files and symptoms that don't have a run() function
        [[ ! "$filename" =~ ^_.* ]] || continue
        grep -Eq "^def run\s*\(.*\):" "$path" || continue
        symptoms+=("${filename%.py}")
    done
    echo "${symptoms[*]}"
}

This bug was fixed in the package apport - 2.27.0-0ubuntu3

---------------
apport (2.27.0-0ubuntu3) mantic; urgency=medium

  * fix: raise "gdb not found" as soon as detected (LP: #2031919)
  * bash-completion: Do not use ls in completion (LP: #1850804)
