[Bug 2095211] Re: partitioning crashed with CurtinInstallError: KeyError DEVNAME

[Olivier Gayot]

Hello,

The following snap revisions have the fix included. The snap build
number is the revision (5th column):

For Ubuntu Server (subiquity)
track    arch     channel    tag                revision
24.04    amd64    stable     24.04.4            7020
24.04    arm64    stable     24.04.4            7018
24.04    ppc64el  stable     24.04.4            7019
24.04    riscv64  stable     24.04.4            7022
24.04    s390x    stable     24.04.4            7021
25.10    amd64    stable     25.10              6871
25.10    arm64    stable     25.10              6874
25.10    ppc64el  stable     25.10              6873
25.10    riscv64  stable     25.10              6875
25.10    s390x    stable     25.10              6872

For Ubuntu Desktop (ubuntu-desktop-provision)
25.10    amd64    stable     0+git.31940d804    441
24.04    amd64    stable     0+git.4bc1f4077    494

For ubuntu-desktop-provision on other architectures (i.e., arm64), snaps
with the same tag should exist  but I don't have access to the revision
numbers.

Thank you
