Delete Branch "%!s()"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?

Describe the issue
I used apt-get to perform an update from 2.0.2 to 2.0.3 and if failed with the error:
multiple lines showing:chown: changing ownership of '/usr/share/audiobookshelf/audiobooks/author/book/file.mp3': Read-only file systemthen finally
chown: changing ownership of '/usr/share/audiobookshelf/audiobooks': Read-only file systemdpkg: error processing package audiobookshelf (--configure):
installed audiobookshelf package post-installation script subprocess returned error exit status 1
I have my audiobooks stored on a NAS and they are mounted in a read only NFS share that is linked to /usr/share/audiobookshelf/audiobooks
Everything else under /usr/share/audiobookshelf is stored with read/write access locally.
I was able to resolve the issue by un-mounting the audiobooks, doing the update then mounting the audio books again, ie:
$ sudo systemctl stop audiobookshelf$ sudo umount /usr/share/audiobookshelf/audiobooks
$ sudo apt-get upgrade audiobookshelf

Calculating upgrade... Done
The following packages were automatically installed and are no longer required:
libfwupdplugin1 libllvm11
Use 'sudo apt autoremove' to remove them.
1 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.
After this operation, B of additional disk space will be used.

Setting up audiobookshelf (2.0.3) ...
Created symlink /etc/systemd/system/multi-user.target.wants/audiobookshelf.service → /lib/systemd/system/audiobookshelf.service.
$ sudo mount /usr/share/audiobookshelf/audiobooks
$ sudo systemctl start audiobookshelf
Does audiobookshelf need to make changes to the actual audio book files?
Steps to reproduce the issue
Audiobookshelf version
v2.0.2
How are you running audiobookshelf?
Debian/PPA
@advplyr commented on GitHub (Apr 25, 2022):
Read-only should be fine. Where are those chown logs coming from? Those logs aren't from abs right?
@cenjui commented on GitHub (Apr 25, 2022):
No, they are from the apt-get command line. I need to check but I think when I do an apt-get upgrade upgrade of abs it downloads the new version and then runs through the package installation commands. In the postinst file at the end it says:
mkdir -p '/var/log/audiobookshelf'
chown -R 'audiobookshelf:audiobookshelf' '/var/log/audiobookshelf'
chown -R 'audiobookshelf:audiobookshelf' '/usr/share/audiobookshelf'
chown -R 'audiobookshelf:audiobookshelf' "$FFMPEG_INSTALL_DIR"
I think it attempts to do this on upgrade as well, normally that wouldn't be an issue if you have a read/write file system but with a read only file system the command fails with exit code 1, which then causes the upgrade to fail.
A fix would be to check if the directory exists in which case either don't make any changes or check if its read only? I would try and fix it myself but my skills are not quite up to it, sorry!
@advplyr commented on GitHub (May 20, 2022):
I rewrote the debian installer to first check if the folders exist before setting permissions.
Hopefully that should resolve this for read-only folders but let me know if not and we can keep working on it.
This is in v2.0.15

This worked perfectly for me updating to v2.0.15 - thank you!
