# 2023-05-19: #3573 -> PR #3582: Ubuntu 23.10's virtualenv 20.23 no longer
|
|
# supports Python 2. Root cause is virtualenv 20.22.0 (2023-04-19) which
|
|
# removed Python 2 support: https://virtualenv.pypa.io/en/latest/changelog.html
|
|
# Unfortunately older versions from Ubuntu 22.04 (#3583) & 23.04 like...
|
|
# http://launchpadlibrarian.net/651276954/virtualenv_20.19.0+ds-1_all.deb
|
|
# ...can drag in newer 20.23+ version of python3-virtualenv, leaving
|
|
# us with /usr/bin/virtualenv 20.23 once again, i.e. preventing Python 2.
|
|
# Whereas pip (which installs /usr/local/bin/virtualvenv) at least works:
|
|
#
|
|
#iif grep -qi ubuntu /etc/os-release; then # Ubuntu 23.10+ (and Mint 22+ ?) needs this. Ubuntu 23.04 tolerates it.
