Maybe a reinstall? Try: apt reinstall mintupdate

Have you installed an older version of python on that machine? Please post the output of the following command:

Code: Select all

python3 -V

Well I thought maybe reinstall libcurl, but 7.68 seems to be correct, that's the one showing in synaptic. Maybe reinstall python3-pycurl. Or see what version is installed with:

Code: Select all

apt list --installed|grep pycurl

Should be 7.43.0.2 if you are on 20.3.

Yep, acerimusdux has the right idea I think, you might want to try apt install --reinstall python3-pycurl.

See these issues for people having similar issues (including me!) https://github.com/linuxmint/cinnamon/issues/10591 https://github.com/linuxmint/cinnamon/issues/10579 https://github.com/linuxmint/cinnamon/issues/10572

The issue always seems to be solved by some form of apt install --reinstall python3-SOMETHING

Reinstalled `python3-pycurl` but facing same issue.

Maybe try the script by Mint dev mtwebster at the bottom of this issue: https://github.com/linuxmint/cinnamon/issues/10591

I'm wondering if you need python-pycurl for anything. That's not installed by default. My machine has python3-pycurl, but not python-pycurl. So maybe try

Code: Select all

apt remove python-pycurl

See if there's anything else that depends on it, or if you can just remove it. Though the traceback shows the problem was with a python3 script, so this likely won't solve it anyway.
