I’ve been dealing with ticket RQF1615983, a request for CERNBOX for Ubuntu 20.04.
The guy Fabrice le Goff, has created a deb package and I’m posting the steps he took:
I compiled cernbox client from the source available for Ubuntu 19.10 in https://cernbox.cern.ch/cernbox/doc/Linux/repo/Ubuntu_19.10/ (cernbox-client_2.5.4+oc.orig.tar.gz patched with cernbox-client_2.5.4+oc-2719.diff.gz) and made a deb package out of it.
tar xzf cernbox-client*.tar.gz
gunzip diff.gz
cd cernbox-client
patch …/*.diff
mkdir client-build
cd client-build
sudo apt-get install ‘.qt5.-dev’ #probably installing a lot of unneeded things but well… lazyness is what it is
sudo apt install libsqlite3-dev
cmake …
make -j
sudo checkinstall
