[Bug 1792497] Re: package shim (not installed) failed to install/upgrade: subprocess dpkg-deb --control returned error exit status 2

[Robie Basak]

The logs here are missing, but I think the likely cause is this:

$ sudo apt-get -f install
Reading package lists... Done
Building dependency tree
Reading state information... Done
Correcting dependencies... Done
The following extra packages will be installed:
  shim
The following NEW packages will be installed
  shim
0 to upgrade, 1 to newly install, 0 to remove and 207 not to upgrade.
3 not fully installed or removed.
Need to get 0 B/440 kB of archives.
After this operation, 2,448 kB of additional disk space will be used.
Do you want to continue? [Y/n] y
dpkg-deb: error: archive '/var/cache/apt/archives/shim_13-0ubuntu2_amd64.deb' has premature member 'control.tar.xz' before 'control.tar.gz', giving up
dpkg: error processing archive /var/cache/apt/archives/shim_13-0ubuntu2_amd64.deb (--unpack):
 subprocess dpkg-deb --control returned error exit status 2
Errors were encountered while processing:
 /var/cache/apt/archives/shim_13-0ubuntu2_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

I can't be certain that this is exactly what the reporter hit, but it
seems likely enough to me that I think it's safe to assume it for now.

Thanks to sam_w on IRC for providing this and finding this bug.
