Hi,
E: Failed to fetch
http://ftp.cc.uoc.gr/mirrors/linux/mx/mx/repo/pool/main/m/mx-docs/mx-doc
s_20200817mx19+1_all.deb
This server only has the predecessor package
mx-docs_20200817mx19_all.deb
It seems that mx-docs_20200817mx19+1_all.deb already has a successor named
mx-docs_20200817mx19+2.deb
http://mxrepo.com/mx/repo/pool/main/m/mx-docs/mx-docs_20200817mx19+2_all.deb
Google found me the currently desired package name as
http://mxl.mirror.root.lu/mx/repo/pool/main/m/mx-docs/mx-docs_20200817mx19+1_all.deb
(If every attempt fails to get this working as mirror, i'd download the
package manually and install it by "dpkg -i".
This might be a bad idea, though. I'm very bad as Debian sysadmin.)
Err:5 http://ftp.gr.debian.org/mirrors/linux/mx/mx/repo buster Release
404 Not Found [IP: 147.102.222.211 80]"
Did i type something wrong, please??
That server does not expose a top level directory named "mirrors".
The directory path for accessing MX repos seems not to be much standardized.
Have a nice day :)
