Description GG HH 2021-04-13 12:55:53 CEST

Lua alternatives links are wrong. They should be updated to 5.3.

$ ll /etc/alternatives/lua*
lrwxrwxrwx 1 root root 15 mars  28 00:22 /etc/alternatives/lua -> /usr/bin/lua5.3
lrwxrwxrwx 1 root root 16 mars  28 00:22 /etc/alternatives/luac -> /usr/bin/luac5.3

$ ll /usr/bin/lua*
-rwxr-xr-x 1 root root  24056 avril  4 08:35 /usr/bin/lua*

Alternatives support was dropped when lua was updated to 5.4. At the same time we dropped lua 5.2 and lua 5.3.

Only the latest lua and lua5.1 are supported. /usr/bin/lua and /usr/bin/luac are always coming from the latest lua version we have and aren't alternatives symlinks anymore.

Proper handling of all alternatives file removal is a bit problematic because of how lua was packaged earlier. I'll try to figure out how to handle updating from older releases better. At least we don't have %postun scriptlet errors or warnings anymore.

Thanks for your learned comments, Jani. Makes me wonder whether this can be closed forthwith; or whether you prefer to leave it open until you manage to concoct something.

Assigning to you because of your existing involvement & work on lua.

Comment 3 GG HH 2021-04-13 22:57:46 CEST

why not just removing deprecated links in pre 5.4 install ?

Comment 4 Jani Välimaa 2021-04-17 21:28:16 CEST

Updating from mga8 should be now smooth. Cauldron users needs to remove leftover files by hand from /etc/alternatives and /var/lib/alternatives.

This might also work even though it will output a warning.
# update-alternatives --remove-all lua
