Re: [SOLVED] /usr/lib/libc.so.6: version `GLIBC_2.34’ not found

Thanks Scimmia and WorMzy for the feedback, I only gave dd mode two tries as a sanity check. I'll give it another go on Sunday. Let's hope I don't need to visit my laptops documentation. Have a good weekend folks.

Often you need to use a hotkey at boot to select a different drive to boot from.

Acer laptops use F12 for that.

F12 worked. Sanity restored for now. Thanks all. Let's hope this goes well.

It worked. Thank you all, this thread was hugely helpful.

I managed to figure out why my laptop wasn't dual booting before (F12 on start up) and upgrade most packages.

Re: [SOLVED] /usr/lib/libc.so.6: version `GLIBC_2.34’ not found

Sorry for bumping this old thread, but I ran something like `pacman -Sy; pacman -S expat` and broke a huge chunk of my system. It's a server, so booting with a live USB or something would be really annoying.

I knew I only messed up this single package, so I checked the pacman log to see which version to downgrade to:

# grep "upgraded expat" /var/log/pacman.log | tail -n1
[2022-12-14T12:18:49+0100] [ALPM] upgraded expat (2.4.8-1 -> 2.5.0-1)

Then, I created a temporary directory and extracted the old package into it (since `pacman -U` was also broken...)

# mkdir /tmp/expat
# cd /tmp/expat
# cp /var/cache/pacman/pkg/expat-2.4.8-1-x86_64.pkg.tar.zst .
# tar --use-compress-program=unzstd -xvf ./expat-2.4.8-1-x86_64.pkg.tar.zst

I copied the /tmp/expat/usr directory contents into /usr:

# cp --backup=numbered -vRT ./usr /usr

Finally, I crossed my fingers and ran `pacman -Suy`, which worked. Such a relief. It's the yearly reminder that `-Sy` is not a good habit.
