Have you now first installed pipewire-jack? What exact commands and output did you use. Post it here please.
Then we move on to solve the next. Your iso is outdated, therefore a lot of packages and conflicts need to be solved if you try updating this, it’s Arch…
Again, search button shows that this problem was addressed previously. We are happy to help if you have questions but pls do some search, topics were already addressed.
now i have this
pacman-conf: /usr/lib/libc.so.6: version `GLIBC_2.34' not found
These are all manual interventions you need to make because the iso is so old and you chose offline. Search the error out.
You could use your old iso.
Do an offline install.
DO NOT UPDATE.
Go into new old system.
Download NEW iso from website.
Flash new iso to USB. You might be able to build Popsicle or some other USB flasher without updating, or good old fashion dd if=new_iso_file of=usb should work just fine.
Reinstall again with up to date iso.
Otherwise as noted by @BONK you could just fix the errors and continue on.
thank you this is exactly what i done and now i have a last OS
