Status changed to 'Confirmed' because the bug affects multiple users.

Could you please include the output of 'apt-cache policy libzstd1'?

[Brian Murray (brian-murray)]

Could you include the output of 'dpkg -S libzstd.so.1' also? Thanks.

[Julian Andres Klode (juliank)]

output of 'ls -l /usr/lib/x86_64-linux-gnu/libzstd.so*' would be nice too

[Julian Andres Klode (juliank)]

Can you please attach the tarball of /var/log/installer?

[Ubfan (ubfan1)]

Note that litzstd is typically the last library in alphabetical order, and this is the third different package reported (see bug 1766046) with this error.

What exact log are you requesting?

[Julian Andres Klode (juliank)]

Mostly /var/log/installer/syslog. It seems your install did not complete and hence the system is broken.
