@fossfreedom thank you for your reply.
This is a brand new Ubuntu Budgie 20.10 install so I would say I’m using default python
user@machine:~$ python3 --version
Python 3.8.6
so no venv or non-default python.
In regards to PPA, thank you for that remark. The only addition has been installing Cryptomator via PPA. For that
PPA: sebastian-stenzel/cryptomator
version 1.5.11 appimage-151
So I would say
cryptomator - 1.5.11-0ppa1 published on 2020-12-15 for Groovy
is the one installed as per link below:

In regard to dependencies:

Description: Multi-platform client-side encryption of your cloud files.
Cryptomator provides free client-side AES encryption for your cloud files.
Create encrypted vaults, which get mounted as virtual volumes. Whatever
you save on one of these volumes will end up encrypted inside your vault.
So you can see dependencies are:
Depends: libc6 (>= 2.3.3), zlib1g (>= 1:1.1.4)
user@machine:~$ apt policy libc6
libc6:
Installed: 2.32-0ubuntu3
Candidate: 2.32-0ubuntu3
Version table:
*** 2.32-0ubuntu3 500
500 http://es.archive.ubuntu.com/ubuntu groovy/main amd64 Packages
100 /var/lib/dpkg/status
user@machine:~$ apt policy zlib1g
zlib1g:
Installed: 1:1.2.11.dfsg-2ubuntu4
Candidate: 1:1.2.11.dfsg-2ubuntu4
Version table:
*** 1:1.2.11.dfsg-2ubuntu4 500
500 http://es.archive.ubuntu.com/ubuntu groovy/main amd64 Packages
100 /var/lib/dpkg/status
One more command:
user@machine:~$ apt-cache depends cryptomator
cryptomator
Depends: libc6
Depends: zlib1g
Conflicts: cryptomator
Recommends: <gvfs-bin>
Recommends: gvfs-backends
gvfs-backends:i386
Recommends: gvfs-fuse
Recommends: xdg-utils
I have not tried apt-rdepends but could do if needed.
I can’t find a way to determine whether libc6 installed version 2.32-0ubuntu3 or zlib1g installed version 1:1.2.11.dfsg-2ubuntu4 are the result of them having been updated by cryptomator. Because, other than that, as indicated above, this is a brand new Ubuntu Budgie 20.10 install.
Thank you for your time and attention in advance,
