[Solved] "Permission denied" in general | Ubuntu 19.10 | snap 2.42.5

nicolaasjk · January 23, 2020, 11:59pm

Hi everyone

Just migrated 2 days ago from Windows 7 to Ubuntu and bumped into AppArmor and Snap-Store problems. In the section about “denied” entries you might start seeing where problems started. I then installed the Hello-World application because I expected that would be the litmus / smoke / sanity test here. If it’s the incorrect group, let me know and I’ll figure out how to update it.

Hope the information is useful.

Note that I have GNOME, KDE, and XFCE installed. Using KDE because I found it did freeze like GNOME for me.

:~$ snap version snap 2.42.5 snapd 2.42.5 series 16 ubuntu 19.10 kernel 5.3.0-26-generic

This is unexpected, I’m not aware of any package shipping a profile AppArmor profile for /usr/bin/snap. Can you collect the output of the following commands?

sudo apparmor_status |grep snap
dpkg -S /etc/apparmor.d/usr.bin.snap

nicolaasjk · January 24, 2020, 8:38am

@mborzecki Thanks for looking at this.

zyga-snapd · January 24, 2020, 8:54am

Can you run:

dpkg -S /etc/apparmor.d/snap

In either case, yes, please remove (or set aside to another directory) the aforementioned snap. Rebooting will fix the issue.

mborzecki · January 24, 2020, 9:16am

As @zyga-snapd mentioned, please remove /etc/apparmor.d/snap and /etc/apparmor.d/usr.bin.snap. I can’t quite figure out why you have both files, given that dpkg belives they weren’t shipped by any installed package.

nicolaasjk · January 24, 2020, 9:30am

@zyga-snapd
Yes, executing “dpkg -S snap” returns ALOT of information.

@mborzecki
I just need to confirm definition of “remove” in this context.

rm snap / rm usr.bin.snap
or
sudo snap remove snap / sudo snap remove usr.bin.snap

I suspect #2 above will return errors.

After the reboot, what should I expect to see when I execute “snap-store” or “freemind”?

Regards,

zyga-snapd · January 24, 2020, 9:31am

Please use the full path. dpkg -S /etc/apparmor.d/snap as well as dpkg -S /etc/apparmor.d/usr.bin.snap

zyga-snapd · January 24, 2020, 9:32am

Use sudo mv /etc/apparmor.d/snap ~/mysterious.snap and sudo mv /etc/apparmor.d/usr.bin.snap ~/mysterious.user.bin.snap and then reboot.

nicolaasjk · January 24, 2020, 9:39am

@zyga-snapd

Different results are returned when including the full path in the commands.

:/etc/apparmor.d$ dpkg -S /etc/apparmor.d/snap
dpkg-query: no path found matching pattern /etc/apparmor.d/snap
:/etc/apparmor.d$ dpkg -S /etc/apparmor.d/usr.bin.snap
dpkg-query: no path found matching pattern /etc/apparmor.d/usr.bin.snap

Running the command from “/etc/apparmor.d/” location the following is returned.

:/etc/apparmor.d$ dpkg -S usr.bin.snap
dpkg-query: no path found matching pattern usr.bin.snap
:/etc/apparmor.d$ dpkg -S snap

This means the file was not shipped by any package. It must have been created by something later on.

[Solved]

Thank you @zyga-snapd and @mborzecki for you help and guidance. Everything mentioned in the original post works now. I will mark the above solutions for other readers.

Is the category “snapd” correct, or should it be “snap” instead since it seems most was related to “snap”?

For record purposes, below are the results after the applying the solution. Not sure what the “illegal” WARNINGS are for and who the maintainers are, but at least the results are consistent with when I started on Ubuntu.

you seem to have installed the snap package alongside with the snapd package … the snap packaging format is only provided by the snapd package, i assume the snap DNA sequencer package has a maintainer (postinst/preinst) script that generates the apparmor profile (which in turn then clashes with the profile for the snap command that snapd ships …)

$ apt-cache show snap
...
Description-en: location of genes from DNA sequence with hidden markov model
 SNAP is a general purpose gene finding program suitable for both eukaryotic
 and prokaryotic genomes. SNAP is an acroynm for Semi-HMM-based Nucleic Acid
 Parser.
...

@zyga-snapd perhaps the packaging should be updated to have snapd add a proper “Conflicts/Breaks” against “snap”

mborzecki · January 24, 2020, 11:35am

We already have

Conflicts: snap (<< 2013-11-29-1ubuntu1)

but it’s clearly not sufficient.

Edit: installed the snap package from 19.10, version 2013-11-29-9. None /etc/apparmor.d/{snap,usr.bin.snap} were created, so it’s still unclear how it ended up in the user’s system.

nicolaasjk · January 27, 2020, 7:58am

@mborzecki

I might be able to help there a bit since I just recent installed Ubuntu 19.10 and my /var/log/apt/history.log file is still relatively short’ish. The order of apt-get executions on record I see are:

1. apt-get --yes -oDebug::pkgDepCache::AutoInstall=yes install linux-generic... [A LOT OF PACKAGES. This may be the initial installation of linux.]
2. apt-get --yes -oDebug::pkgDepCache::AutoInstall=yes install linux-generic... [A LOT OF PACKAGES. This may be the initial installation of linux.]
3. apt-get install tasksel
4. apt-get install sddm
5. apt-get -o APT::Status-Fd=4 -o APT::Keep-Fds::=5 -o APT::Keep-Fds::=6 -q -y -o APT::Install-Recommends=true -o APT::Get::AutomaticRemove=true -o APT::Acquire::Retries=3 install kubuntu-desktop^
6. apt-get -o APT::Status-Fd=4 -o APT::Keep-Fds::=5 -o APT::Keep-Fds::=6 -q -y -o APT::Install-Recommends=true -o APT::Get::AutomaticRemove=true -o APT::Acquire::Retries=3 install xubuntu-desktop^
7. apt-get install htop
8. apt-get install libgl1-mesa-dri:i386 libgl1-mesa-glx:i386 libc6:i386
9. apt-get install monodevelop
10. apt-get install fpc
11. apt-get install lazarus
12. apt-get install kdevelop

At this point, I used Snap-Store to install FreeMind and ran into the issue where FreeMind could not access removable devices. I saw Snap-Store provided some very basic permissions, but no permissions for accessing removable media. This is when I first read about AppArmor and tried to “solve” the permission issue. One thing lead to another…

13. apt-get install apparmor-utils

At this point I think I tried to revert permissions to default. 14. apt-get install --reinstall apparmor At this point Snap-Store GUI didn’t load anymore.

15. apt-get install --reinstall snapd

At this point, I took a break from improving my 4-letter vocabulary and focused on getting my migration done on the things I still can. During this period I got in contact with the AppArmor and Snapcraft team.

16. apt-get install handbrake-gtk
17. apt-get install handbrake-cli
18. apt-get remove openjdk-8-jre-headless
19. apt-get install openjdk-8-jre
20. apt-get install simplescreenrecorder
21. apt-get install python-tk
22. apt-get install cups-pdf

Hope this helps with the forensics.

Regards,
