This is a bit of shameless self-promotion, but I think that anyone running an +ArchLinux machine will probably appreciate this.
+ +As anyone who has run ArchLinux knows, there is a common phenomenon of +upgrading your system and things breaking. If it's just some awkward behavior of +some of the tools you can typically resolve it with ease, but there have been +times for myself when, because I use Nvidia drivers, I cannot even get my +graphical environment running and I have to revert the last upgrade. Most of the +time, however, I've had to do this manually, since I did not know of any tool +that does it, at least not the way I wanted, which is just an automatic undoing +of the last pacman transaction.
+ +To remedy this problem I decided to write a hobby script that would do this +work for me based on the pacman logs, using the local cache and even the +ArchLinux Archive if the package cannot be found locally. I've even added +support for my AUR helper of choice, yay.[1] This +script is called pacundo and can be found in my personal +repository[2] as well as in the AUR for an easier +installation.[3]
+ +As of right now (pacundo v1.1) the script only supports bare pacman and yay, +but if you use a different AUR helper and want to contribute this functionality +for your favorite AUR helper, feel free to send me a patch following the +contributing guidelines.[4] As noted there, you +can also find a mirror of my repository on GitHub[5] +where I can also receive issues and pull requests (but please read the notes +about pull requests that I wrote in the contributing section mentioned above).
+ +Hopefully this helps out a few people to fix their ArchLinux systems. I've +also run it on Manjaro and it seems to work fine there as well, and my guess is +it should work on any ArchLinux derivative distribution.
+ +God bless, and happy hacking!
