Public bug reported: I've just helped a group of Ubuntu 20.04 users with Microsoft Surface devices. They rely upon a github repository releases pocket as the apt archive. Those users recently hit a bug "Ubuntu: Apt update fails with Error 401 Unauthorized" [1]
The initial simple Github URL gets a Location: redirect to a complex URL with un-escaped query-string. The resulting complex URL causes apt to fail to fetch the resource. $ sudo apt upgrade -y Err:1 https://pkg.surfacelinux.com/debian release/main amd64 libwacom-surface amd64 1.12-2 401 Unauthorized [IP: 185.199.110.133 443] The URL can be manually corrected. One of the Surface users provided this example: bad: https://objects.githubusercontent.com/github-production-release- asset-2e65be/139604852/86019e52-7bfa-4bc6-8cc1-52147027aee6?X-Amz- Algorithm=AWS4-HMAC-SHA256&X-Amz- Credential=AKIAIWNJYAX4CSVEH53A/20211105/us- east-1/s3/aws4_request&X-Amz-Date=20211105T161053Z&X-Amz- Expires=300&X-Amz- Signature=2bc0c28946db539ada250b1030c37249dae909d73a68c90b5e7bfe7fecd5d347&X-Amz- SignedHeaders=host&actor_id=0&key_id=0&repo_id=139604852&response- content-disposition=attachment; filename=libwacom- surface_1.12-2_amd64.deb&response-content-type=application/octet-stream good: https://objects.githubusercontent.com/github-production-release- asset-2e65be/139604852/86019e52-7bfa-4bc6-8cc1-52147027aee6?X-Amz- Algorithm=AWS4-HMAC-SHA256&X-Amz- Credential=AKIAIWNJYAX4CSVEH53A%2F20211105%2Fus- east-1%2Fs3%2Faws4_request&X-Amz-Date=20211105T160935Z&X-Amz- Expires=300&X-Amz- Signature=44d9307e66dfb5b3672ee0082b8801ad2532ac4b6be61c3442fb265ffce72852&X-Amz- SignedHeaders=host&actor_id=0&key_id=0&repo_id=139604852&response- content-disposition=attachment%3B%20filename%3Dlibwacom- surface_1.12-2_amd64.deb&response-content-type=application%2Foctet- stream I found this also affects a github repository I recently added for Zotero on 20.04. The problem is fixed in later versions of apt upstream, in Debian and Ubuntu releases. I cherry-picked the 4 commits [3] and provided a package for Focal in my PPA [2] which multiple users have reported (in [1]) solves the issue. It would be really good to get those patches included in 20.04 as an SRU. As the code is in later versions of apt and is focused on the URL encoding only it has minimal potential for causing regressions.
