A few days ago I tried to upgrade my home theatre PC (HTPC) running Arch Linux using pikaur. To my surprise pikaur failed with a TypeError message, for the most part this just simply doesn’t happen. I didn’t think much of it as I just re-install pikaur and carried on my way. The next day I experienced the same issue again on my main system. This time I decided I would venture out to understand the situation better.
Environment
Tested using the following…
- Arch Linux x86_64
- Fish v3.5.1
- GNU bash v5.1.16
- Pikaur v1.13.2
Assumptions
- Steps prefixed with a “$” (dollar sign) represents the CLI (command-line interface) prompt
- The text after the “$” is to be entered at the CLI
- Understanding how to use an AUR helper (e.g. Pikaur)
Problem
When running the following pikaur command a TypeError message is returned.

raise TypeError(
TypeError: 'AURPackageInfo' does not have attribute 'submitter'
Solution
Simply re-install pikaur following my knowledge base article, Arch Linux Install AUR Helper. Once this has been completed pikaur will function again as normal.
I found confirmation from pikaur project issue #680, TypeError: ‘AURPackageInfo’ does not have attribute ‘submitter’. I was not able to figure out anything more on the direct cause of the error.
After the re-install of pikaur I have the following version.
$ pikaur --version
Pikaur v1.14.5.r1.g40c98ca
