Please describe the problem.
When trying to operate one of my repositories I'm getting this error:
git-annex: thread blocked indefinitely in an MVar operation
error: external filter 'git-annex filter-process' failed
What steps will reproduce the problem?
Any of the git-annex commands I've tried, such as fsck.
What version of git-annex are you using? On what operating system?
I was running 10.20230126-3 on Debian Bookworm, but I've tried upgrading to 10.20241202-1~bpo12+1 from bookworm-backports in the hope that'd fix it.
Please provide any additional information below.
I've enabled debugging, and this appears to be the relevant lines (running git annex status):

The only SQLite3 database I can find is in .git/annex/keysdb . I can open that using sqlite3 and select from the tables with no error messages. Is there another file it is trying to access?
Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
I've been happily using git-annex for many many years, first time I've encountered an issue like this.
Hey,
I hit this again today, running 10.20230126-3, so I upgraded to 10.20250115-1~bpo12+1. New error messages, excellent! Including: The SQL trying to be run, and the error from sqlite.
This included "disk I/O error" from sqlite. Further investigation, and the volume was out of space 🤦. Don't know if that was the case when I first hit this or not.
Cheers, Andrew
You can delete the sqlite database affected by the problem and git-annex will recreate it as needed.
Given the improved error message shows what the problem is now, I don't know what more can be done about this really.
