Public bug reported:
We received an email from the upstream maintainer of squashfs-tools
requesting that we include the lastest upstream release (4.7.5) in
Ubuntu. Some excerpts follow:
---
If possible it would great to have Squashfs-tools 4.7.5 added to 26.04,
this is because it fixes some nasty bugs that people will almost
certainly hit with Squashfs-tools 4.7.4 when Ubuntu 26.04 is released.
[...]
I also noticed that Michael backported one of the nasty bug fixes to
1:4.7.4-1ubuntu1
* Backport "mksquashfs: don't create duplicate virtual -> real disk
mappings" which causes corrupt squashfs files to be built when building
Ubuntu Studio (LP: #2143762)
This is bug 2.i in the Squashfs-tools 4.7.5 changelog
(https://github.com/plougher/squashfs-tools/blob/master/CHANGES.md).
If you cannot get Squashfs-tools 4.7.5 added to Ubuntu 26.04, would it
be possible to back-port the other two critical bug fix patches from
4.7.5, which are:
* https://github.com/plougher/squashfs-
tools/commit/1824bef68dabf665f07e48d6ac90dc917639dada
This is bug 2.ii in the Squashfs 4.7.5 changelog
This bug breaks a common use case which is reading a disk partition (or
whole disk) using Mksquashfs

* https://github.com/plougher/squashfs-
tools/commit/9b3e403128812632aca6df86e1602d15f63432a4
This is bug 2.iii in the Squashfs 4.7.5 changelog.

The relevant version is in Debian already so this is trivial to action.
The diff is quite large: https://pastebin.canonical.com/p/z2hZFqzcZB/
and we should probably at least give it a quick skim for reasonableness.
At least it doesn't contain any large binary blobs afaics...
