Need to update version (bionic). This is 2.6.5 and the latest official one as FlatPak is 3.3.5.
Works perfectly, in opposite to the Flatpak version which does not even start on Mint 20.2 Cinammon, though it takes much more disk space. I like this version.
im usining it since nextcloud exist. It do the job and do it well.
For me is the best open source cloud client ever! Para mim é o melhor cliente cloud open source que existe!
