[Bug 2060120] Re: Unmet dependencies cause gparted to fail to install

[Juozas Pocius]

Currently the noble repositories are the mostly broken, related to
recent xz backdoor cve (CVE-2024-3094). Meanwhile you may want to add an
override to your apt configuration, create a file in
/etc/apt/preferences.d with contents similar to below, where pinning >
1000 would mean package could be downgraded if there's a version from
more preferred archive.

$ cat /etc/apt/preferences.d/apt-pinning 
Package: *
Pin: release a=noble-updates
Pin-Priority: 1002
Package: *
Pin: release a=noble
Pin-Priority: 1001

You may add noble-security override to the above file if you want to be
future proof, make sure priority is higher (1002 or 1003) than on noble
archive

Package: *
Pin: release a=noble-security
Pin-Priority: 1003

Also after creating this configuration and updating apt repositories
apt-cache policy should be similar to below assuming you're using only
main ubuntu repositories (noble, noble-security, noble-updates, noble-
backports) and nothing else more.

$ apt-cache policy

Finally apt-cache policy for gparted & gparted-common packages should be
like this as long as you have the modifications above and also after
repositories are no longer broken it'd be safe to undo the modification.

$ apt-cache policy gparted gparted-common
gparted:
  Installed: (none)
  Candidate: 1.5.0-1
  Version table:
     1.5.0-1 1002

gparted-common:
  Installed: (none)
  Candidate: 1.5.0-1
  Version table:
     1.5.0-1build2 1001
