I've had a similar thing happen to me when installing Koha with (what were then) current versions of Ubuntu and Koha. I can't remember the exact modules, but this is the gist of what happened: When I tried to install MariaDB (a), I got a message saying that it was dependent on MariaDB (b), which was not going to be installed. When I tried to install MariaDB (b), I got a message saying that it was dependent on MariaDB (c), which was not going to be installed. My solution was to install MariaDB (c), then MariaDB (b), then MariaDB (a). Worked like a charm--no problem, lovely budgie. What made it a lot easier was that Ubuntu actually told me the file it needed, which made installing it a lot easier. Something like "Error: You have made an error." wouldn't have been as helpful.

Hello,

I am trying to install the Koha common package while upgrading from 20.11 to 21.05 on Ubuntu 18.04.5. However, during the installation, the error returned is that some dependency packages will not be installed. Therefore, koha-common does not install as a result. See the message below in bold italicized.

*"Some packages could not be installed. This may mean that you have* *requested an impossible situation or if you are using the unstable* *distribution that some required packages have not yet been created* *or been moved out of Incoming.* *The following information may help to resolve the situation:*

*The following packages have unmet dependencies:* * koha-common : Depends: libmojolicious-plugin-openapi-perl but it is not going to be installed* * Depends: libnet-oauth2-authorizationserver-perl but it is not going to be installed* * Depends: libyaml-libyaml-perl but it is not going to be installed* *E: Unable to correct problems, you have held broken packages."*

Any ideas on how to resolve this? _______________________________________________
