spotify-client dpkg post-installation script error code 1

[tosmaz]

Operating System

Linux pop-os 5.4.0-7634-generic #38~1595345317~20.04~a8480ad-Ubuntu

I encountered error as described in title on reinstallation from apt (I removed deb, and wanted to try out flatpack and snap versions of app. Don't bother to do it, apt/deb version integration is by far the best.).

Also I couldn't be sure if it affects reinstalls only or Ubuntu 20.04 installs in general.

As it turns out piece of postinst script fails. I managed to narrow down piece of script that failed:
```

# Add Spotify repository nondestructively

# Let users opt-out of adding a repository with:

# sudo touch /etc/apt/sources.list.d/spotify.list

SOURCE="/etc/apt/sources.list.d/spotify.list"

if [ ! -e "$SOURCE" ]; then

# Check if there is already an active source configuration

# and only add one if we can't find one

if ! grep -v -E '^\s*#' /etc/apt/sources.list /etc/apt/sources.list.d/*.list 2>/dev/null | \

grep -q -E 'deb\s+.*https?://repository(-origin)?.spotify.com\s+(stable|testing)\s+non-free'

then

tee "$SOURCE" >/dev/null 2>&1 <<EOF

deb http://repository.spotify.com stable non-free

EOF

fi

fi
```

Commenting it out allowed install to complete.

If you encounter such issue you probably could comment affected piece of script as rest works fine. Script is located in /var/lib/dpkg/info/spotify-client.postinstall. After commenting out affected script you could try to finish installation with:
# dpkg --configure spotify-client
I did that myself, but i don't know if it has any unforseeable side effects, do it at your discretion.
