[Bug 2098630] [NEW] [RC] Two copies of every snap are shipped

[Simon Quigley]

Public bug reported:

When doing some ISO content checks this cycle for Lubuntu, I noticed
something strange:

$ sudo ls -lahR /var/lib/snapd/ | grep "\.snap"
[...]
-rw------- 2 root root 4.0K Feb 16 19:24 bare_5.snap
-rw------- 2 root root  74M Feb 16 19:24 core22_1748.snap
-rw------- 2 root root 259M Feb 16 19:24 firefox_5751.snap
-rw------- 2 root root  12M Feb 16 19:24 firmware-updater_167.snap
-rw------- 2 root root 517M Feb 16 19:24 gnome-42-2204_202.snap
-rw------- 2 root root  92M Feb 16 19:24 gtk-common-themes_1535.snap
-rw------- 2 root root  45M Feb 16 19:24 snapd_23545.snap
-rw------- 2 root root 4.0K Feb 16 19:24 bare_5.snap
-rw------- 2 root root  74M Feb 16 19:24 core22_1748.snap
-rw------- 2 root root 259M Feb 16 19:24 firefox_5751.snap
-rw------- 2 root root  12M Feb 16 19:24 firmware-updater_167.snap
-rw------- 2 root root 517M Feb 16 19:24 gnome-42-2204_202.snap
-rw------- 2 root root  92M Feb 16 19:24 gtk-common-themes_1535.snap
-rw------- 2 root root  45M Feb 16 19:24 snapd_23545.snap

There are *two* copies of every single snap on the ISO. And they are not
symbolic links.

I thought, perhaps this is a consequence of my ISO bootup, perhaps snapd
likes to put them there for some reason?

Nope:

$ sudo unsquashfs -ls /cdrom/casper/minimal.standard.squashfs | grep "\.snap"
[...]
squashfs-root/var/lib/snapd/seed/snaps/bare_5.snap
squashfs-root/var/lib/snapd/seed/snaps/core22_1748.snap
squashfs-root/var/lib/snapd/seed/snaps/firefox_5751.snap

squashfs-root/var/lib/snapd/seed/snaps/gtk-common-themes_1535.snap
squashfs-root/var/lib/snapd/seed/snaps/snapd_23545.snap
squashfs-root/var/lib/snapd/snaps/bare_5.snap
squashfs-root/var/lib/snapd/snaps/core22_1748.snap
squashfs-root/var/lib/snapd/snaps/firefox_5751.snap
squashfs-root/var/lib/snapd/snaps/firmware-updater_167.snap
squashfs-root/var/lib/snapd/snaps/gnome-42-2204_202.snap
squashfs-root/var/lib/snapd/snaps/gtk-common-themes_1535.snap
squashfs-root/var/lib/snapd/snaps/snapd_23545.snap

This is a release blocker for Lubuntu 25.04 and Lubuntu 24.04.3. Whether
this is a snapd bug or livecd-rootfs bug, there must only be one copy of
each snap installed.
