There’s an appimage for their manager app there. You might also try using Distrobox to give yourself access to a distro that uses apt, and then add Yubico’s PPA and install the software from there. I don’t know whether it would work but in principle it should.
It seems to be characteristic of the Gnome project’s philosophy to do things in what they consider the best way rather than the way a new user might expect. It’s an admirable commitment to deliberate design rather than copying, but it may also make it unappealing to some users. Personally I don’t enjoy using Gnome, but I know people who love it. Thankfully in the Linux world we have options.
OpenSUSE Tumbleweed has been my desktop home for the last year. It’s very up to date, yet it’s somehow solid and reliable despite sometimes receiving hundreds of updates per week. And if anything goes wrong with an update you can easily roll back to a BTRFS snapshot. It has a good repository supplemented by Flatpaks, and I haven’t had any problems finding software, yet it’s not a hassle like some other cutting-edge distros. It uses KDE Plasma by default, which I consider a plus. I came to it from Mint, which was my go-to distro for a long time, but I enjoy Tumbleweed more for its up-to-dateness and configurability, and I have (surprisingly) encountered more software gaps on Mint.
It came as Gaza’s health ministry said that at least 15,899 Palestinians, 70% of them women or under 18s, have now been killed in Israeli air and artillery strikes on the enclave since Oct. 7. Thousands more are missing and feared buried in rubble.
Whatever this is, it’s kind of walking like a genocide and quacking like a genocide.
