Unfortunately I cannot install anything. I used the command line and
the app but neither of them will work. I have no idea what to do next.
I used su and sudo first. It just keeps saying it cannot connect with
the base from which I get updates, etc. I used the reinstall on brasero
and it just said that it was up to date. I am so confused.

The Wanderer, in an earlier post (04/28/2023 at 19;02), suggested
reinstalling the base-files package. I believe this is the correct
procedure, at least to start with. It should be relatively free from
any risk of doing further damage to your system. The same post also
suggested you might need to reinstall other packages if they had
created subdirectories under /var that are not included in the
base-files package, That also should not significantly risk any
further damage. Reinstalling installed packages sometimes helps and in
my experience (almost 30 years now) is unlikely to be harmful.
Reinstalling base-files (and other packages as needed) also should
correct any permission problems that may have crept in.
How to reinstall a package depends on how you maintain or upgrade your
system.
If you use synaptic or aptitude, both have reinstall options that you
can choose from the menu or submenu you would use for a new package
installation.
If you log in as root on a terminal or terminal emulator to install
and upgrade software, the command would be
apt install --reinstall <name of package> - for example,
apt install --reinstall base-files
If you use sudo in a terminal or terminal emulator to maintain
software, use the above commands prefixed by "sudo" as you normally
would for actions that need administrator privileges.
This should reinstall the version of the base-files (or other named
package) that matches the most recently installed version.
I think the reinstall process might sometimes pause to ask you to
choose between installing the default configuration file from the
package or keeping an existing one that you might have changed. It
should be safe to keep the one already installed.
If you have questions about any of this, feel free to ask, either
privately or on the list.

Reinstalling the base-files package should create or correct the
following directories under /var:
/var
/var/backups
/var/cache
/var/lib
/var/lib/dpkg
/var/lib/misc
/var/local
/var/lock
/var/log
/var/run

Do not look at the NUMBERS.
OWNER.
GROUP.
PERMISSIONS.
The numbers mean nothing.

See that? Group write. Set-group-id. Group staff. Probably not a
big
deal, because who the hell uses /var/local for anything, but there is
no excuse for not checking the OWNER, GROUP and PERMISSIONS.
