Snap is broken on install aarch: arm64 vmdk

[trewchainz]

Hope this is the right place. snap gives pkg mgr access to pentesting/other tools not available in apt or apt-get (i.e. john-the-ripper).

When snapd is installed with apt install snapd, the service fails to start. The root of the cause is in its dependency with apparmor. apparmor is missing crucial files in /etc/apparmor.d/tunables/. apt install --reinstall apparmor will not fix this.

Additionally, there's another conflict that prevents snapd.service from running which is the /etc/fstab file. There are incomplete/old version duplicate entries which confuse snapd.service when reading /etc/fstab.

Workaround

• Purge, remove residual files, install apparmor and snapd

sudo apt purge apparmor snapd
sudo rm -rf /etc/apparmor.d /var/lib/snapd /snap
sudo apt install apparmor snapd

• Edit /etc/fstab and comment out the incomplete/old duplicate entries

$cat /etc/fstab
