I am on a Ubuntu 18.04 LTS system and yesterday I finally decided to get the newest Macaulay2 via the ppa named above. So I entered on the command-line
and afterwards installed the 1.24 version of Macaulay2 via the Synaptic package manager.
Macaulay2 seems to work fine, but there was an issue during the installation process - at two times an error message came up, but went away too fast for me to remember. Now I am trying to investigate the reasons for the error and did
sudo apt-get update
which gave me (after other output that seemed ok):
Err:11
https://math.illinois.eduMacaulay2/Repositories/Ubuntu bionic InRelease
Could not resolve 'math.illinois.eduMacaulay2'
Reading package lists... Done
W: Failed to fetch
http://www.math.uiuc.edu/Macaulay2/Repositories/Ubuntu/dists/bionic/InRelease Could not resolve 'math.illinois.eduMacaulay2'
W: Some index files failed to download. They have been ignored, or old ones used instead.
Analyzing the output in the line starting with Err:11 there must be some typo in the play, which changed 'edu/Macaulay2' into 'eduMacaulay2'. I tried to find it in the files
/etc/apt/sources.list
and
/etc/apt/sources.list.d/macaulay2-ubuntu-macaulay2-bionic.list
which were the only Macaulay related files in the /etc/apt hierarchy I was aware of, but the typo was not there.
Did anybody else notice a similar problem after trying to use the ppa and/or what can I do to investigate the problem further (I already consulted ChatGPT which gave some plausible advice but finally could not solve the issue).
Many thanks in advance for all tips and hints!
