Comment 22 for bug 1849753

FYI, if people need to workaround this to get real work done, you can add something like this to your bashrc:

snap_workaround() {
    fn="/var/lib/snapd/apparmor/snap-confine/lp1849753"
    test -e "$fn" && return

    tmpfn=$(mktemp)
    cat > "$tmpfn" <<EOM
# lp1849753
unix,
owner /** rw,
ptrace readby peer=unconfined,
EOM
    echo "Moving workaround rules to '$fn'"
    sudo mv "$tmpfn" "$fn"
    echo "Reloading snap-confine policy"
    sudo apparmor_parser -r /etc/apparmor.d/*snap-confine* /var/lib/snapd/apparmor/profiles/snap-confine.*
    # another mysterious issue where sometimes all the policy isn't loaded (eg, with rustup)
    echo "Reloading all snap.* policy (work around missing profiles)"
    sudo apparmor_parser -r /var/lib/snapd/apparmor/profiles/snap.*
    sudo apparmor_parser -r /var/lib/snapd/apparmor/profiles/snap-update-ns.*
}
