2020-11-01: Fixing Nextcloud Client on OpenBSD xkp
================================================================================

I use nextcloud to sync files between systems. I could use rsync or unison but
I like nextcloud despite the bloat. My old OpenBSD install worked fine with the
owncloudclient package. I decided to try the new nextcloudclient package.

I had a problem. It kept asking for passwords. I used ktrace to see what was
happening:

ktrace -C

$ ktrace -t cinpstuxX nextcloud

I then used kdump(1) to make a dump, piped to less and I searched for strings
relating to password, keychain etc.

I finally found a reference to kwalletd5 not being present. I installed the
kwalletmanager package, ran it and created a new wallet. Now nextcloud starts
up without me having to reauthenticate every time.
