I was trying to install yelp-tools. I ran sudo apt-get update && sudo apt-get upgrade then sudo apt-get install yelp-tools it fails with this:
E: Failed to fetch http://security.ubuntu.com/ubuntu/pool/universe/libx/libxml2/python3-libxml2_2.9.13%2bdfsg-1ubuntu0.2_amd64.deb 404 Not Found [IP: 220.127.116.11 80]
sudo apt-get install --fix-missing yelp-tools returns the same error.
looking in the repo: there is no package for libxml2_2.9.13%2bdfsg-1ubuntu0.2_amd64.deb
rather it is: libxml2_2.9.13%2bdfsg-1ubuntu0.3_amd64.deb
I would suspect somewhere, there is a package listing pointing to a package that doesn't exist due to a typo.
where is the index file for the repo
http://security.ubuntu.com/ubuntu jammy-security universe
apt-get update updates the package index files. where are those index files exactly? I think there is a typo in one of them.
the problem goes on, from there, but its all the same type of error. I installed the newer libxml2_2.9.13%2bdfsg-1ubuntu0.3_amd64.deb package, then installed yelp-tools and it worked. but I think there must be an error in the package index, should I contact someone? how can I verify?
