On Ubuntu 20.04, the configure script suggests me this: configure: hint: installing the following system packages is recommended and may avoid building some of the above SPKGs from source: configure: $ sudo apt-get update $ sudo apt-get install libflint-arb-dev libbrial-dev libbrial-groebner-dev coinor-cbc coinor-libcbc-dev libcdd-dev libcdd-tools cliquer libcliquer-dev curl libcurl4-openssl-dev libec-dev eclib-tools gmp-ecm libecm-dev fflas-ffpack libflint-dev flintqs libgf2x-dev gfan libgivaro-dev glpk-utils libglpk-dev pari-gp2c libgsl-dev libiml-dev lcalc liblfunction-dev libatomic-ops-dev libbraiding-dev libgd-dev liblrcalc-dev libm4rie-dev libmpfi-dev nauty libntl-dev libopenblas-dev palp pari-gp2c libpari-dev pari-doc pari-elldata pari-galdata pari-galpol pari-seadata libplanarity-dev planarity libppl-dev ppl-dev python3.7 libpython3.7-dev python3-distutils r-base-dev r-cran-lattice librw-dev libsqlite3-dev sqlite3 libsuitesparse-dev libsymmetrica2-dev sympow tachyon yasm libzmq3-dev libzn-poly-dev
When, I run the above command, I get the following errors (it replaces python3.7 by python3.7-2to3 and ibpython3.7-stdlib, but it does not recognize the rational expression libpython3.7-dev): Note : sélection de python3.7-2to3 pour l'expression rationnelle « python3.7 » Note : sélection de libpython3.7-stdlib pour l'expression rationnelle « python3.7 » E: Impossible de trouver le paquet libpython3.7-dev E: Impossible de trouver de paquet correspondant à l'expression rationnelle « libpython3.7-dev » E: Impossible de trouver de paquet correspondant à l'expression rationnelle « libpython3.7-dev » -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
