Alire issue with directories causing exception

Has anyone seen this?

There is no index, it can’t download it for some reason.

Could you rerun your first issue with -d? I may be able to look into it.

Did you change something? I’m not able to understand why you have “//” in /home/laguest/.config//alire/indexes/community/repo

Better yet. Open an issue on the alire github Issues · alire-project/alire · GitHub

AdaOrbit · July 2, 2026, 3:08pm

I don’t know how you did it but having two “//” in the file path throws off alire. Specifically Dens assumption that a filepath cannot be empty and only has one “/” per directory depth.

(I’ll have to see if I have enough time to recreate this with alire master)

Maybe try to remove the index with alr index --del=community and then alr index --reset-community

Lucretia · July 2, 2026, 3:22pm

Yeah, I noticed the ‘//’

This only does this on the latest alr, on 1.3.0 it’s fine.

There is no index to delete.

AdaOrbit · July 2, 2026, 3:28pm

The latest alire release is 2.1.1 The website hasn’t been updated but on the github release page you can download your version.

It may already be fixed since then have been a few den updates.

RREE · July 2, 2026, 3:28pm

I also recently had a problem with alr (v2.1.0) that it could not update the index anymore. I don’t remember the details of the error messages, however.
The solution was to manually remove the community index (rm -rf ~/.config/alire/indexes/community) and to download it again (alr index --reset-community)

Lucretia · July 2, 2026, 4:06pm

Yeah, I tried that by moving both the ~/.config/alire and the ~/.local/share/alire dirs and trying again, same issue.,

Lucretia · July 2, 2026, 4:09pm

Downloaded 2.1.1.

I tried to remove the old directories, seems it didn’t create one inside ~/.local

So, it got a bit further in creating the indexes directory.

could you give me the output of cat ~/.config/alire/settings.toml ?

It seams like alire had an issue reading the config file

I’m getting out of ideas… Could it be that your .config is a symlink or some permission issue?

Nope, I literally deleted it above and re-ran the alr command as above, it created it from scratch as I showed.

does alire2.1 work again after setting the index with alire3?

No,

$ ./bin/alr -d index --reset-community

This is ~/bin/alr just unpacked from the 2.1.1 archive, the previous bin was in the alire source directory after building it.

I now really confused… It works on my machine

What is the output of cat ~/.config/alire/indexes/community/index.toml ?

Lucretia · July 2, 2026, 6:33pm

$ cat ~/.config/alire/indexes/community/index.toml
name = "community"
priority = 1
url = "git+https://github.com/alire-project/alire-index#stable-1.4.0"

I’ve got a feeling I’ve had this exact issue before but cannot remember what the solution was. But the version from git works, so will use that.
