Fails to install when there is no main branch

[theaino]

Affected Version

paru v2.0.3 - libalpm v14.0.0

Description

When installing a package with no main branch (for example conan) it failes to install.

When manually installing the package (makepkg -si), it works.

Output

aino@arch ~ » paru -S conan

This was also happening in yay. It basically happens when the aur repo for some reason is in a detached head state. Then, git merging causes an error. In yay I managed to fix it by adding a git branch --show-current statement and checking if it returns anything, only then merge.

I guess you'd have to fix it in aur_fetch
