### Fixes
- Arch:
- search: not able to find installed packages that were renamed on the repositories (e.g: xapps -> xapp)
- not able to replace an installed package for a new one that replaces it during conflict resolutions (e.g: xapp replaces xapps)
- AUR: not able to find some repository dependencies when their names are not an exact match (e.g: sc-controller [0.4.7-1] relies on "pylibacl". This dependency now is called "python-pylibacl")
