7.4 SNAP Problem Solving
Cloud servers as virtual machines running on top of real machines seem to have an incorrect setup for snaps creating a scope within the virtual environment within which they are expecting to run:
$ firefox
/user.slice/user-1000.slice/session-818.scope is not a snap cgroupThe solution is to “correct” one environment variable, DBUS_SESSION_BUS_ADDRESS:
$ echo $DBUS_SESSION_BUS_ADDRESS
unix:abstract=/tmp/dbus-y5iyFDRQhP,guid=d834ce543237a562627324f2583f5134Set it as below and all is good:
Then start the snap installed app (firefox in this case).
sudo snap remove –purge
Generate a list of installed snaps:
```bash
snap list | awk 'NR > 1 {print $1}'Your donation will support ongoing availability and give you access to the PDF version of this book.
