-  :: [package name] package(s) failed to install. +I just use [[vim#vimdiff]] to check difference between the current and new files. You could also just use ''vim -d [file] [file]''. ''Ctrl+w [left or right arrow]'' to switch window, btw.
-  :: ensure package version does not mismatch between .SRCINFO and PKGBUILD +
-  :: ensure package name has a VCS suffix if this is a devel package+
  
-Are are [[tool:software:pacaur]] problem, and can get gotten round by installing manually, or by using another helper+You can get a nice list of ''.pacnew''s with ''find /etc -regextype posix-extended -regex ".+\.pac(new|save)" 2> /dev/null''

 +To clear Pacman's cache ''pacman -Sc''. 
 + 
 +You can use Paccache (in [[arch>community/x86_64/pacman-contrib/pacman-contrib/|pacman-contrib]]) to have better control over what you do with cached packages. Egs.: ''paccache -rk 2'' will delete everything except the last two versions of a package. ''paccache -ruk0'' will remove everything for packages that are no longer installed.

 +==== Keys ==== 
 + 
 +If you get errors about keys (and things like files being corrupt), try updating ''archlinux-keyring'' before doing a full update. EG: (''sudo pacman -Sy archlinux-keyring && sudo pacman -Su''. You might want to chuck that in an alias.

 +nbjp [[https://monthly-reports.archlinux.page/2022/07/|Apparently Arch now updates the keyring weekly]]. 
 + 
 +I was getting this error: ''warning: Public keyring not found; have you run 'pacman-key --init'?'' which was mucking up the upgrade process. These steps fixed it: 
 + 
 +  - ''sudo rm -r /etc/pacman.d/gnupg'' 
 +  - ''sudo pacman-key --init'' 
 +  - ''sudo pacman-key --populate archlinux'' 
 +  - ''sudo pacman -S archlinux-keyring'' 
 + 
 +==== AUR ==== 
 +=== .SRCINFO and PKGBUILD mismatch === 
 + 
 +Errors like 
 +

-==== Speeding Up Package Building ==== +==== Broken Pacman After Partial Upgrade ==== 
-  * [[archw>Makepkg]] + 
-    * [[archw>Makepkg#Improving_compile_times]] +When doing a partial upgrade to get my keyring in order before a proper upgrade I mistakenly upgraded pacman too. This ca'us an error where the version of glibc that pacman needed was out of whack with the one I had installed, so pacman would not work at all. 
-    * [[archw>Makepkg#Utilizing_multiple_cores_on_compression]]+ 
 +To fix this I downloaded a //static// version of pacman and ran a fresh ''# pacman -Syu'' and that fixed everything.
