There is a problem while trying τo upgrade the system. Specifically, slapt-get tries to download aaa_libraries-15.1-x86_64- 40 (or aaa_libraries-15.1-i686-40 in Slackel-32 bit), which is nowhere to be found, because according to ChangeLogs this was rebuilt to aaa_libraries-15.1-x86_64- 41 , as of 1 ...

Both issues are gone. Thank you Dimitri!

For some time (about 1.5 month) I was quite busy and had not much time for computing, so I didn't update my Slackel installations. Today it was finally time to do so, and I have two issues:
In 32-bit Slackel, package wpa_supplicant won't upgrade because MD5 checksum is missing. I guess the reason ...

Today's system update upgraded the kernel to 6.6.11, and Grub was automatically updated as expected (even in 64-bit). I have no idea why Grub didn't update in 64-bit last time and I had to do it manually, but now it works.

As for the kernel 6.1.66 I mentioned as "latest" for 32-bit that was because ...

Just before I did a routine system upgrade in both 32- and 64-bit. No problem at all in 32-bit, but in 64-bit (real installation on disk) I get this:
pap[~]$ install-upgrade-kernel upgrade huge
...
< kernel upgraded from 6.6.9 to 6.6.10 here >
...

mv: not replacing '/boot/grub/grub ...

tree-sitter was already a dependency since emacs 29.1-1, reported here. This one is new in 29.1-2. Thank you Dimitri!

Upgrading from emacs 29.1-..-1 to emacs 29.1-...-2 makes Emacs not working anymore. However installing libdeflate solves the problem. So I guess libdeflate should be added as a dependency for emacs.

After 8+years using Slackel, I finally decided to change the all-green straw wallpaper (which I still like) to the Rio-Antirrio bridge photo, which seems to be the new default wallpaper.

Update: The problem while upgrading the kernel in 32-bit does not appear anymore, at least since kernel 6.1.55. And was also upgraded to the newer 6.1.57 without any issues. I'm going to assume it was a kernel problem.

It must be a VM issue then? Since glibc 2.36 I no longer have a real 32-bit Slackel installation (because I can't).
