Unable to build packages #25

Closed KSaiAkshit closed 3 years ago

KSaiAkshit commented 3 years ago

I have recently switched over from Ubuntu 20.04 to Arch (ArcoLinux) and i am trying to get ROS working on Arch but to no avail. I followed the instructions on this page, but keep running into errors. I've tried building it via Paru but i get the same error of unmet dependencies. I have added arch4edu to my /etc/pacman.conf and updated it. None of the other "ros bundles" work either.

I'd greatly appreciate if someone could help me

AchmadFathoni commented 3 years ago

I heard people got trouble from arch4edu. Are you really need arch4edu?

I don't really know, the official Ros-wiki page does mention it and i did add the repo.

AchmadFathoni commented 3 years ago

Ok, first. I want you to remove your arch4edu from your arch. I never add third party repo such as arch4edu so you must find how to do it yourself. Google it!

Now try install ros-noetic-desktop-full again using paru. Tell me the output.

This is what i get when ran using yay without arch4edu

AchmadFathoni commented 3 years ago

Yeah this is the exact error people get when installing arch4edu. Now install genmsg by yay -S ros-noetic-genmsg

KSaiAkshit commented 3 years ago

I had already removed arch4edu from pacman.conf, but I could install genmsg

Ok, to be safe I think you should clear your cache by running rm -rf ~/.cache/yay/ros-noetic-*

Do you have same error as before when installing this package?

AchmadFathoni commented 3 years ago

If you still have same error then uninstall every ros-noetic-* packages from your arch then try to install ros-noetic-rosgraph-msgs again.

If you still have same error try to reinstall your arch linux then install yay then install ros-noetic-desktop-full again. DO NOT use arch4edu

How do I uninstall all of them? pacman -R ros-noetic-* ?

I can't use sudo pacman -Rsc ros-melodic-* , it returns package not found.

AchmadFathoni commented 3 years ago

yay -Rs $(yay -Qm | grep ros | cut -f 1 -d " ")

AchmadFathoni commented 3 years ago

Then yay -Yc

KSaiAkshit commented 3 years ago

yay -Rs $(yay -Qm | grep ros | cut -f 1 -d " ")

sudo pacman -Rsc $(pacman -Qs ros- | awk ' NR % 2 == 1 { print substr($1, 7) } ') i found this on AUR page

KSaiAkshit commented 3 years ago

Then yay -Yc

This will removing a lot of stuff that have nothing to do with ROS, so i didnt proceed with this.

AchmadFathoni commented 3 years ago

It removes unused dependency. Yeah you may do that, tell me when you success building ros-noetic-desktop-full

KSaiAkshit commented 3 years ago

What do i do after removing said stuff? yay -S ros-noetic-desktop-full ?

AchmadFathoni commented 3 years ago

Yes

AchmadFathoni commented 3 years ago

Does it work?

KSaiAkshit commented 3 years ago

Does it work?

Nope, not happening :cry:

AchmadFathoni commented 3 years ago

Yeah maybe just reinstall your arch, or use Ubuntu instead

KSaiAkshit commented 3 years ago

I have switched over from Ubuntu actually 😅 Guess Ubuntu it is✌️ Thanks for the help I am closing this issue

AchmadFathoni commented 3 years ago

Well, I've tried to install ros via arch4edu. I got the same error as above. The fix is actually simple:

  1. Delete arch4edu from pacman.conf
  2. Delete ~/.cache/yay/
  3. Delete all ros package and its dependency yay -Rs $(yay -Q |grep ros- | cut -d " " -f1 && yay -Yc
  4. Update database yay -Syyu
  5. Install ros yay -S ros-noetic-desktop-full --noconfirm --sudoloop @KSaiAkshit seem you miss the step 4
