Rolf,
Asking here is the Right Thing (TM) but I am in at this moment between two differen things (one of them being dinner...) so I have to come back to this but regarding > Package libcurl-dev is a virtual package provided by: > libcurl4-openssl-dev 7.68.0-1ubuntu2.6 > libcurl4-nss-dev 7.68.0-1ubuntu2.6 > libcurl4-gnutls-dev 7.68.0-1ubuntu2.6 > You should explicitly select one to install. I have also found that confusing. I somewhat recently helped a very motivated undergrad getting an R package working which required a (available for Ubuntu, good thing there) library which itself libcurl4-gnutls-dev. I happen to have libcurl4-openssl-dev installed and they don't coexist ... so I opted to doing that work with the undergrad in a Docker environment. Long story short, I would suggest trying to see if you can work with / can get what you need adjusted to libcurl4-openssl-dev. On my Ubuntu (21.04) system: edd@rob:~$ apt-cache rdepends libcurl4-openssl-dev | wc -l 22 edd@rob:~$ apt-cache rdepends libcurl4-gnutls-dev | wc -l 45 edd@rob:~$ So maybe my preference is on the wrong side of the tracks too. I don't fully understand why these cannot coexist...
