summary: Ensure that `snap advise-snap` works
details: |
`snap advise-snap` searches for a snap that provides the given
command line or package name. This test verifies that the database
downloaded from the store used by `advise-snap` is readable to all
users. It verifies that it can lookup by both command lines and
package name. And it verifies that it can work as a replacement
for `command-not-found`.
# On some slow external devices the test fails to restart snapd on restore
backends:
- -external
# advise-snap / command-not-found only works on ubuntu classic, and on uc16
# on uc18+ we don't have the /usr/lib/command-not-found symlink so it's not
# useful
systems:
- ubuntu-1*
- ubuntu-2*
- ubuntu-core-16*
