First Cup of Ubuntu
Hi,
I recently upgraded to Ubuntu 24.04.1 LTS and noticed that when I try to run the man command after the upgrade, I get the following error message:
Code:man: error while loading shared libraries: libmandb-2.10.2.so: cannot open shared object file: No such file or directory
I've tried manually copying the file from another machine into thedirectory. Also tried purging man and reinstalling. Still get the error.Code:/usr/lib/man-db/
Anyone else seeing this?

Not seeing what you are seeing about man-db.
No need to copy from other machine. If necessary, just reinstall.
Show results between code tags -
Code:apt show man-db && apt policy man-db

Thanks for the reply. Already tried purging and reinstalling, no luck. Here's the output from apt:

This looks like root of your issue...
Not sure , but maybe this will fix it...man: error while loading shared libraries: libmandb-2.10.2.so: cannot open shared object file: No such file or directory

That file is in the man-db package

If you run:
What is the output?Code:updatedb locate libmandb

For some reason, it wants libmandb-2.10.2.so, but libmandb-2.12.0.so is what's installed.Code:ryan@home:~$ sudo updatedb [sudo] password for ryan: ryan@home:~$ locate libmandb /usr/lib/man-db/libmandb-2.12.0.so /usr/lib/man-db/libmandb.so ryan@home:~$ cd /usr/lib/man-db/ ryan@home:/usr/lib/man-db$ ls -l total 296 -rw-r--r-- 1 root root 267008 Apr 8 2024 libman-2.12.0.so lrwxrwxrwx 1 root root 16 Apr 8 2024 libman.so -> libman-2.12.0.so -rw-r--r-- 1 root root 30864 Apr 8 2024 libmandb-2.12.0.so lrwxrwxrwx 1 root root 18 Apr 8 2024 libmandb.so -> libmandb-2.12.0.so lrwxrwxrwx 1 root root 13 Apr 8 2024 man -> ../../bin/man lrwxrwxrwx 1 root root 15 Apr 8 2024 mandb -> ../../bin/mandb
