GPGME error possibly related to libgcrypt update. Can't pacman :(

I'm getting the GPGME error: Invalid crypto engine message.
I just recently updated a pc that has limited diskspace (5G on / ) and has been dormant for 3 months.  Due to both of those factors, when I went to do an update of packages I had to do it piecemeal such that the download and extraction didn't fill up the / partition. I must have dorked up the system with the piecemeal upgrade because after updating libgcrypt in one of my updates I began to  get this error.
To get around the problem I simply set SigLevel = Never in /etc/pacman.conf as suggested by other posts. I completed the upgrade and put back SigLevel to its previous status. However when I tried a simple litmus test I still see that there are GPGME errors.

[arch@arch ~]$ sudo pacman -Syu feh

I'm not sure what else to post to aid in finding the root problem.

I've stumbled upon several posts dealing with this issue from about a year ago but none have helped me solve it.

Any help resolving this is appreciated.

What happens if you do delete the package?

It just gets deleted.  If I try again then it still fails because it can't validate the PGP signature.

I feel like you are hinting that the package may be corrupted in the download. I think the package in and of itself is fine.  I think the failure is simply due to the libgcrypt problems.

I'm too lazy to read your whole post, so have you tried booting to archiso and updating from the live system (not a chroot to the install) using the -r flag?

OPTIONS
...
       -r, --root <path>
           Specify an alternative installation root (default is /). This should not
           be used as a way to install software into /usr/local instead of /usr.
           This option is used if you want to install a package on a temporarily
           mounted partition that is "owned" by another system.  NOTE: If database
           path or log file are not specified on either the command line or in
           pacman.conf(5), their default location will be inside this root path.

In the future (once the installed system is working again) you could try specifying a different CacheDir if /var/cache/pacman/pkg is on the same fs as / .

@inkdinky, did you ever find a solution to this problem? I'm running into the same issue all of sudden and have not been able to figure out how to fix it. Setting `SigLevel = Never` allowed me to update, but putting it back left me in the same state.

Ran into the same issue. Had to

rm -r /etc/pacman.d/gnupg
pacman-key --init
pacman-key --populate archlinux

to make it work again. Not sure how/ if the keyring got corrupted though.
