[SOLVED] I accidentally deleted "CIFSPlugin.pm"

[JohnB17]

I accidentally deleted "CIFSPlugin.pm" and now it says this when I try to start one of my VMs:

Can't locate PVE/Storage/CIFSPlugin.pm in @INC (you may need to install the PVE::Storage::CIFSPlugin module) (@INC contains: /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.28.1 /usr/local/share/perl/5.28.1 /usr/lib/x86_64-linux-gnu/perl5/5.28 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.28 /usr/share/perl/5.28 /usr/local/lib/site_perl /usr/lib/x86_64-linux-gnu/perl-base) at /usr/share/perl5/PVE/Storage.pm line 32, <DATA> line 755.

How can I undo my mistake?

Actually, I figured I could just install Proxmox Virtual Environment into a VM, then copy the file off of the vhd.

FYI, if that ever happens again you can also just reinstall the package:

apt update
apt install --reinstall libpve-storage-perl

If you're unsure which package then first search the file <-> package map:

dpkg -S CIFSPlugin.pm
# or if ambiguous, then with the full path:
dpkg -S /usr/share/perl5/PVE/Storage/CIFSPlugin.pm

Actually, I tried

apt install --reinstall libpve-storage-perl

but it had errored out, so that's why I went the vm route.

That could be due to possibly missing the apt update and/or missing valid package repository entries in general.
